Slay the Spire 2 patch notes

The latest Slay the Spire 2 update is Beta Patch Notes - v0.111.0, posted Aug 14, 2026. Below are Mega Crit's patch notes from Steam, newest first: beta patches roughly every two weeks, hotfixes, and the major updates that reach the main branch.

Beta Patch Notes - v0.111.0 · Aug 14, 2026

Time for another beta patch! Heads up that there won't be a patch on the 27th as our team is taking a break in the last week of August. As we'll explain a bit further in the upcoming August Neowsletter, there may be a longer wait in general for the next patch, as we've shifted our focus to some BIG, much-anticipated pieces of content!

In the meantime, let's look at some of this update's highlights. First off, there are a couple of card reworks and lots of various balance changes as well as UX and performance improvements. Also, we have officially implemented Indonesian localization! In the art and VFX realm, we've added some cool new card art and, excitingly, low HP idle animations for all of the playable characters! Now when you're close to death you'll at least have some fun visual flair to go along with it.

We look forward to hearing all of your feedback! Now on with the rest of the patch notes...

Beta Patch Notes - v0.108.0 · Jul 3, 2026

For all you beta testers who have been chomping at the bit for a new patch to chew on... here it is! Today's beta patch brings a ton of fixes, balance changes, some UX additions, a BIG batch of new multiplayer cards, and new art additions--including some animations for the latest boss, Aeonglass!

We've also got some big updates in the modding realm to call out...

Modding Updates

Thank you to our incredible community of modders (and mod players) for all of your feedback since we released Steam Workshop support! We've got quite a few changes that will be relevant to modders at the bottom of the notes, but first we wanted to specifically call out some major fixes and changes that affect players.

Previously, when launching the game with mods enabled for the first time, it appeared as though your progress was wiped. That is because unmodded saves are saved separately from your modded ones as a protective measure, and we defaulted to having the modded saves start entirely from scratch. Now, your unmodded saves are automatically copied over to the modded saves and a popup appears to explain the process to new mod users. They are still saved separately, though, which means any progress you make when playing with mods enabled will not be reflected after switching to unmodded and vice versa.

Additionally, players have been frequently encountering version conflict errors when doing modded multiplayer runs. We're introducing some fixes which should reduce those instances and more detailed error popups when they do occur. Note that we still recommend having the same exact mods enabled as your teammates, particularly if they actually affect gameplay and are not merely cosmetic.

We plan for these changes to come to the main branch soon, so non-beta-testers can keep an eye out for that! For more info on modding and playing with mods, check the patch notes from Major Update 2. Now it's time for the rest of today's patch notes...

CONTENT & BALANCE

This means that, if a player would die to self-Doom (ex. from Neurosurge card) but also has an Orb with an end-of-turn passive that would kill the last remaining enemy (ex. Lightning Orb while the enemy is at 3 HP), they will now win the combat instead of losing it after ending their turn

Major Update #2 - v0.107.1 · Jun 19, 2026

Hey Slayers, our second major main branch update is here with 4 patches in 1 (not including hotfixes)! While we'll be covering a lot of things that beta players will already be used to, there are also a few big changes that will be totally new for everyone. One of those has been highly requested by the community in the past few days and another has been very highly requested by the community in the past few months, so let's get into it!

RNG Rework

Ed here, one of the Mega Crit engineers. It turns out that everyone complaining about receiving Debt too often from Neow's Bones was right! We did, in fact, have some unusual RNG problems.

Huge shoutout to tckmn for doing the research - their eight-hour descent into madness was an entertaining watch, and we wouldn't have caught the issue without it. If you're interested in the nitty-gritty, read tckmn's full writeup. Here is a short version.

Most games, including STS2, use pseudo-random number generators (PRNGs). A PRNG is fed a seed value, and given the same seed value, a PRNG will always generate the same sequence of random numbers.

Each run has one primary “run seed”, a sequence of twelve numbers and letters. However, a run actually contains multiple PRNGs that individually influence your deck draw, your combat rewards, your event choices, and the rest of the random elements in the run. Each one uses a seed derived from the run seed.

Since we fed different seeds to each PRNG, we expected their results to be completely unrelated. But we were wrong, and it turns out that our strategy allowed players to predict outcomes given knowledge of unrelated parts of the game.

Let’s visualize one example: the correlation between your first act and the curse you receive from Neow’s Bones. In both cases, we generate a decimal between 0 and 1, but from different PRNGs.

- For your first act, if the decimal generated is less than 0.5, you get Overgrowth; otherwise, you get Underdocks.

- For Neow's Bones’ curse, we use the decimal to pick from a list of ten curses. Between 0 and 0.1 you get Clumsy, between 0.1 and 0.2 you get Debt, and so on.

Here is a scatterplot of the raw numbers generated given 10000 random run seeds on v0.103.3:

There is clear correlation in this result. For example, if our act roll is >0.5 (we’re in the Underdocks), then it’s highly likely that our Neow’s Bones curse roll will be <0.5, which cuts the potential curses you can obtain in half.

Aside from the balance ramifications: once knowledge of this exploit is out there, players are naturally incentivized to use it to play optimally. We don’t want to encourage rote memorization of correlation tables, as it is tedious and unfun.

Thus, in v0.107.1, we replaced our PRNG implementation with a more modern one (xoshiro256**). The resulting scatterplot is evenly distributed, exhibiting no human-detectable correlation.

Rest assured that your suffering is now truly random!

Speaking of updates that will be new to all players, I’ve also been busy working on support for…

Steam Workshop

We built STS2 with modding in mind, and the game has had an integrated mod loader from day one. It's been awesome seeing the outpouring of creativity from the community! But we purposefully haven't been advertising mod support, as we knew it still needed some work.

Previously, the only supported way to install mods was to download them and place them next to the executable. With this patch, Steam Workshop support has officially been added! Now, you can browse and install mods directly from the workshop, and they will be automatically downloaded to all devices where you play on Steam.

If you are a mod creator, upload your mods using the tool here.

And if you're interested in playing some mods, check out the new workshop.

That’s all the updates from Ed! Passing it off to Casey to introduce…

The Bestiary

Casey here! This patch brings in the Bestiary, which Beta testers will already be familiar with. This was a much requested feature for the first game, but at the time I didn't want to create it as there wasn't a good delivery mechanism for an overarching story. However, in the world of Slay the Spire 2, we have a lot more on the narrative side, more creature animations, etc. so we've been hard at work creating this final screen in the compendium (outside of the Achievements page, which is to come much later).

Currently, players can find a list of monsters they've encountered here as well as their moves and animations. In the future we plan to include all sorts of information about the game's enemies, including stats and lore.

Enemy Changes

As many of you have heard by now, The Doormaker has been removed from the game. As we said in the patch notes of the beta patch that brought this change: while Doormaker had interesting micro decisions in the fight, he was over the complexity threshold of what we want and had lingering issues. We decided that starting over fresh will let us hit what we actually want for an Act 3 boss.

Thus a new boss, Aeonglass, is here! We don't want to spoil it too much for non-beta testers, so that's all we're gonna say.

Another big change you'll notice is Hive's Infested Prism enemy has been totally reworked--but again, no spoilers here.

Alright, now it's time to get into the nitty gritty notes!

Beta Patch Notes - v0.107.0 · Jun 4, 2026

Another bi-weekly beta patch is here! This one is a bit smaller as it is intended to lay the groundwork for moving the beta branch to the main branch. Therefore, these updates are mostly focused on stability: a lot of bug fixes, UI/UX/QOL additions, and performance improvements along with just a few balance changes and art additions....

Beta Patch Notes - v0.105.0 · May 8, 2026

It's beta patch time!

For those new to Slay the Spire 2, keep in mind that these changes are pushed to our Beta branch to ensure stability, then eventually merged into the main branch. For those who play using controller, we highly recommend using the Beta branch as we're trying to resolve crashes related to selection screens when playing via controller/Steam Deck.

While our focus is still on fixing crashes and ensuring the game runs on as many hardware configurations as possible, let's look at some of this patch's highlights.

Bi-Weekly Patching

As you've probably noticed, we're moving to patch every 2 weeks rather than weekly as outlined in our Early Access Disclaimer. This may be a bit surprising as the first game patched weekly, but it was a lot of work so it really sucked.

Anyways, the 2-week cadence should make it less hectic for us, allowing bigger changes and more time working and polishing stuff before it goes out. It also allows more time for beta players to absorb and give feedback on changes.

The Bestiary

This week brings... the Bestiary! While it's still an outline of what it will end up being, we hope that seeing these monsters and their animations and data (not yet implemented) all listed in a separate screen will be fun.

Pro Tip: Press the 1 - 8 keys when you're viewing a monster.

Doormaker Out, Aeonglass In

Doormaker has been replaced with a brand new boss, Aeonglass! While Doormaker had interesting micro decisions in the fight, he was over the complexity threshold of what we want and had lingering issues. We decided that starting over fresh will let us hit what we actually want for an Act 3 boss.

CONTENT & BALANCE

General

The Bestiary is now available in the Compendium

Silent

Nerfed Blade of Ink card: Inky enchantment damage decreased from +2 -> +1

Regent

Slightly reworked Sword Sage card:
Old: Sword Sage - Power - Cost 2(1) - Rare - "Sovereign Blade now hits an additional time."
New: Sword Sage - Power - Cost 2(1) - Rare - "Sovereign Blade gains Replay 1."
Among other things, this means that Sword Sage card now has synergy with Parry card
Nerfed Bulwark card: Block decreased from 13(16) -> 12(15)
Buffed Crescent Spear card: base damage increased from 6 -> 8
Nerfed Patter card: Block gain decreased from 9(11) -> 8(10)
Buffed Royalties card: Gold Gain from 30(35) -> 30(40)

Defect

Buffed Infused Core relic: now also gains "Lighting Orbs deal 1 additional damage."
Buffed Hyperbeam: damage increased from 26(34) -> 28(36)
Buffed Shatter card: now Evokes all of your Orbs twice
Buffed Tesla Coil+ card: damage decreased from 6 -> 4, but Lightning Triggers increased from once -> twice
Buffed Uproar card: damage increased from 5(7) -> 6(8)

Colorless Cards

Buffed Gold Axe card: in multiplayer, now deals damage equal to the number of cards played by ALL players, not just cards played by its owner

Enemies

Reworked Doormaker to a new boss, Aeonglass
Changed Fossil Stalker: in multiplayer, now gains a set amount of Strength if it hits any player, instead of gaining Strength for each player hit
Changed Haunted Ship: now applies 3 Weak on Turn 1 instead of applying Weak when it attacks
Buffed Soul Fysh: Scream move damage increased from 11(12) -> 13(15)

Ancients

Reworked Tezcatara's Pumpkin Candle relic
Old: "Gain 1 Energy at the start of each turn. Extinguishes at the start of Act 3."
New: "Gain 1 Energy at the start of each turn. Extinguishes after 5 combats. Can be Kindled at rest sites."
Added new Neow relics:
Kaleidoscope (temp name) - "Upon pickup, gain 2 card rewards with cards from other characters."
Fishing Rod - "Every 3 normal combats, Upgrade a random card in your Deck."
Silken Tress - "Enchant all cards in the first card reward with Glam."
Moved Tezcatara's Seal of Gold relic to option 3 so that it is in the same pool as Pumpkin Candle

Events

Added new power art for Smoggy

Added a more informative error popup for Steam BadCert error in multiplayer
If you move a current_run.save with a modded character in it back to unmodded, you get an error instead of a black screen

WRITING

Reworded Axebot death message to reflect that there is only 1 of them now

Beta Patch Notes - v0.104.0 · Apr 24, 2026

Hey Slayers, we're back to updating the beta branch this week! Here's an overview of our goals with this patch.

On Ascensions

When it comes to general balance, the base difficulty is quite hard right now. We're continuously adjusting this baseline difficulty to make it more accessible for a wide range of players, while also continuing to deliver a challenging game at the highest Ascensions.

Similarly to the first game, completing runs of Slay the Spire 2 at the highest difficulty should feel like a monumental achievement for a fraction of players devoted to understanding the ins and outs of the game's mechanics. Upon beating your first run, we added a message to communicate this intention for the Ascension system.

On Doormaker

We are currently monitoring the Doormaker and looking at a combination in-game feedback, social media posts, and metrics. We want to give players time to adjust a bit, otherwise we'll be balancing around kneejerk reactions. Currently, from looking at millions of runs, Doormaker's overall difficulty/winrate is in a good place (slightly weaker than the other Act 3 bosses both in kill rate and damage dealt). However, we do want to ensure that its mechanics aren't too abrasive against certain playstyles.

Miscellaneous

In other news, we've also got a few card reworks, new Badges, and a balance pass (notably, a Neow's Fury buff is here). One oft-requested feature we've added is an error message when in-game feedback is not received (for instance, if a player is offline), so that should make it clearer when your feedback was actually able to be properly submitted. We've also got a ton of fixes for various crashes and bugs as well as cool new art for some cards (and a certain Ancient)!

CONTENT

General

Added three more Badges
Damage Leader - Dealt the most damage to enemies in multiplayer.
Debuffer - Applied the most Debuffs in multiplayer.
C-c-c-Combo - Played 20 cards in a single turn.

Ironclad

Reworked Conflagration card:
Old: Conflagration - Attack - Cost 1 - Rare - Deal 8(9) damage to ALL enemies. Deals 2(3) additional damage for each other Attack you've played this turn.
New: Conflagration - Attack - Cost 1 - Rare - Deal 2 damage to ALL enemies 4(5) times.
Reworked Drum of Battle card:
Old: Drum of Battle - Power - Cost 0 - Uncommon - Draw 2(3) cards. At the start of your turn, Exhaust the top card of your Draw Pile.
New: Drum of Battle - Skill - Cost 1 - Uncommon - Draw 2 cards. When this card is Exhausted, gain 2(3) Energy.

Anthony's note: Drum of Battle was previously the lowest picked Uncommon Ironclad card, and generally unpopular. This rework attempts to put it into a more interesting spot and adds some synergy to Exhaust decks. Conflagration had low pick rates and middling win rates for a Rare, while also feeling more like an effect that belonged on the Silent (caring about number of card plays). It has been reworked into a simple AOE card that can act as a Strength payout. The numbers will likely need tuning to get into a desired spot, but this should feel like a more appropriate part of the Ironclad's kit.

Regent

Reworked Parry card:
Old: Parry - Uncommon - Power - Cost 1 - Whenever you play Sovereign Blade, gain 10(14) Block.
New: Parry - Uncommon - Power - Cost 1 - Sovereign Blade now gains 10(14) Block.
This means Parry's Block is displayed on the Sovereign Blade card and is now also affected by powers like Dexterity and Frail.

Anthony's note: Parry's numbers are looking correct now, but we think it will be more fun showing the effect on the Blade itself. Relics and powers now being able to interact with the Block should open up new fun interactions. As a result of this change, its numbers may need further tweaking in the future, but we will start with it as is.

Enemies

Reworked Axebots combat to have just a single, more challenging Axebot

BALANCE

General

Terminal run modifier can no longer bring a player below 1 HP

Silent

Changed Nightmare card: if you play it and select a card with an Affliction on it, that Affliction is now removed from the copies added to your hand the following turn
Buffed Untouchable card: upgraded Block gain increased From +2 -> +3

Regent

Changed Tyranny card: now triggers before Bombardment card
This means that if, for example, Tyranny exhausts Bombardment, Bombardment will be played immediately after
Nerfed Reflect card: Block decreased from 17(21) -> 16(20)

Ancients

Buffed Neow's Booming Conch relic: in addition to drawing extra cards, now gains 1 Energy at the start of Elite combats
Buffed Neow's Fury card: instead of selecting randomly now allows you to choose which 2 cards will be put into your Hand from your Discard Pile (you may also now choose fewer than 2 cards if you want)
Buffed Tezcatara's Nutritious Soup relic: in addition to making your Strikes cost 0 and giving them Eternal, now makes all your Strikes deal 3 additional damage

Enemies

Nerfed Ruby Raider Assassin: damage decreased from 11(12) -> 10(11)
Changed Scrolls of Biting: have slightly less HP at low Ascension but slightly higher HP at high Ascension, changed from 31(32) - 38(39) -> 30(33)-37(39)
Changed Owl Magistrate: now has slightly less HP at low Ascension, but slightly higher HP at high Ascension, changed from 234(243) -> 231(247)
Changed Slimed Berserker: now has slightly less HP at low Ascension, but slightly higher HP at high Ascension, changed from 266(276) -> 261(281)
Nerfed Vantom at lower Ascensions:
Dismember move damage decreased from 27(30) -> 26(30)
Slippery power goes from 9 -> 8(9)
Nerfed Waterfall Giant: now heals less at lower Ascension, HP healed changed from 15 -> 10(15)

Anthony's note: We are slowly starting the process of making lower Ascensions a little easier, and high Ascensions slightly harder. We want to do this gradually instead of all at once.

Major Update #1 - v0.103.2 · Apr 17, 2026

It's time, Slayers. All of the content, changes, and fixes from the beta branch over the past month are finally coming to the main branch of the game.

Thanks to the feedback and metrics from our dedicated beta testers (instructions for joining the experimental beta branch can be found here, we feel that the beta version has been shaped into a stable enough position for main branch players to try out the changes. This is still an Early Access game, so just because something made it from beta to main does not mean it's set in stone. We continue to rely on the experiences of players across both branches to eventually get the game into its final, ideal state, just like we did with StS1. Trust the process! And don't forget to press F2!

These "patch notes" will be a little different: this patch encapsulates all of the changes from v0.100.0 to v0.103.1, so if you've been keeping up with the beta patches this post will basically act as a recap. If you haven't been keeping up and you're interested in seeing more detailed, chronological notes for each of these changes, please take a look through the previous beta patch notes. Manually listing out every single difference between the previous and current main versions of the game after so much beta content has gone through reworks, balance changes, and reverts has proven very time-intensive and inefficient. Therefore, we thought we'd give you more of a high-level overview of the biggest changes since the last main patch was released. The beta patches will continue to contain our usual lists of specific patch notes. Let us know if this method of patch note delivery works for you all!

CONTENT & BALANCE

Be sure to pay close attention when embarking on your next few runs: many things that you've grown used to have been re-balanced, reworked, or even removed (in a couple rare cases). However, quite a few new pieces of content have also been added for you to dig into. While we don't get into the nitty gritty of every change, we've listed the biggest relevant highlights.

In terms of general changes, here are a few big things to note:

Ascension 6 has been reworked from Gloom - "Less rest sites." -> Inflation - "Removing cards from your deck at the Merchant is more expensive."
All shop relics now cost 25 gold less and gold-generating relics can no longer appear in the shop
Map generation has been improved and made to be more consistent
If you return to a run after updating with a newly deprecated card in your deck, it is now replaced with a placeholder Status card - "Draw 1 card. Remove this from your Deck. Exhaust."

The Ironclad has received a new card, Not Yet: "Rare - Skill - Cost 2 | Heal 10(13) HP. Exhaust." Some other cards of his--Dominate, Expect a Fight, Spite, and Stoke--have received reworks, while Grapple has been deprecated. Numerous cards have seen buffs, nerfs, and rarity changes. Many of these changes have come with the aim of giving him better survivability and Exhaust synergies.

The Silent's Blade of Ink card has been reworked to generate Shivs enchanted with Inky - "This card deals 2 additional damage and applies 1 Weak." Her classic Acrobatics card has been changed from Common to Uncommon, bringing it more in line with the other cards in its family: Skim, Parse, Glimmer, and Burning Pact. She's also seen a few other buffs and nerfs. Our goal is to make Sly builds less overly dominant while making sure they still feel satisfying.

The Regent's Arsenal card has been reworked from giving Strength based on Colorless cards played to any cards created. In a similar vein, his Regalite relic now grants Block for any card created, not just Colorless cards. Notably, his card pool has seen more buffs than any other character with just a couple of nerfs, which should address concerns about him feeling weaker than the other characters.

The Necrobinder has received a rework for Borrowed Time: "Uncommon - Cost 0 - Skill | Apply 3 Doom to yourself. Gain 1(2) Energy." -> "Uncommon - Cost 1 - Skill | Gain 4(6) energy. Cards cost an additional energy this turn." This new version should go particularly well with high cost cards like Reap and Bury and help to flesh out other ways to play Necrobinder. Aside from that, she's received a handful of buffs and nerfs.

The Defect has seen the least amount of changes of any of the characters, receiving just a couple of buffs and nerfs.

Some Colorless cards, relics, and potions have seen buffs, nerfs, changes, and pool/rarity shifts, with the Hidden Gem card and Pendulum relic receiving reworks. Various events have had their options or spawn conditions tweaked.

There have been a few balance changes to some Ancient offerings, but most notably Neow will now offer 5 new relics:

Hefty Tablet: "Choose 1 of 3 Rare cards to add to your Deck. Add 1 Injury to your Deck."
Neow's Talisman: "Upgrade 1 of your Strikes and 1 of your Defends."
Neow's Bones: "Upon pickup, gain 2 random Neow Relics. Add 1 random Curse to your Deck."
Phial Holster: "Upon pickup, gain 1 potion slot and procure 2 random potions."
Winged Boots: "You may ignore paths when choosing the next rooms to travel to 3 times."

Last but certainly not least, it's time to talk about enemies. While certain enemies have seen some buffs and nerfs, like the Skulking Colony, the Doormaker has seen the most drastic reworks.

ART

Our artists have been hard at work updating the game's placeholder assets (as charming as they are). Many cards, relics, enemies, and even Nonupeipe the Ancient have received some official visuals!

There have also been some really cool additions to enemy animations as well as VFX for certain character moves. Speaking of VFX, card afflictions have also received some fancy new visuals. There are even character-based VFX for energy counters now!

USER INTERFACE & EXPERIENCE

There have been a ton of additions (and even overhauls) when it comes to UI and UX.

First of all, a brand new system for things called Badges has been implemented. Badges may appear at the end of a run, noting various things that happened during a run like defeating a boss without losing HP, beating the game quickly, specific easter eggs, or pointing out that you forgot to spend your gold. They're meant as little reminders to let you know what was unique about each adventure.

Building off of that, leaderboards have been totally revamped. The leaderboards will now only show your friends' scores. We'll add a way to view global scores later. In general, we don't really want to incorporate invasive anti-cheat protection into the game so it's sort of impossible for us to prevent people putting in the maximum score.

Secondly, no more magic numbers. While there are still points accrued for unlocking new cards and such, the score that's sent to the leaderboards and how it's sorted is based on whether you won, how many badges you accrued, and how quickly you finished the run (in that order). This should clarify why you did better on a Daily run compared to your friends.

Because the schema has changed, leaderboards between main branch and beta branch will be separate going forward. We'll eventually add more features like sorting and whatnot, but in the meantime, do let us know what you think of these changes!

Other major changes include the addition of a Phobia Mode setting, the in-game feedback tool's maximum character count increasing from 500 to 8000, the removal of the ability to unlock achievements and epochs in Daily or Custom runs, and various improvements to controller support.

WRITING

Most of the writing-related changes have come in the form of slight rewording to make it clearer what certain cards, relics, potions, and powers actually do. For instance, those who have been confused as to why their Fairy in a Bottle potions haven't saved them from The Insatiable can now understand that the potion only triggers if your HP reaches 0, not if you die by any other means.

BUG FIXES

Many, many various bug fixes have been released, including a fix for the common "Fatal Error" Steam cloud sync issue and multiple crashes, softlocks, and black-screen startup issues. You'll also notice that a myriad of gameplay bugs have been addressed, such as ones related to the logic of Vakuu's Whispering Earring relic.

If you prefer to play on controller, you should find that various navigation problems have now been fixed. In the multiplayer realm, we've fixed some bugged gameplay interactions, state divergence problems, and have resolved many "Error 5008" disconnection issues.

As always, we greatly appreciate your in-game feedback, and will rely on it as we return to releasing more content and experimental changes on the beta branch.

Beta Hotfix Patch Notes - v0.103.1 · Apr 16, 2026

Hey Slayers, we've got a quick beta branch hotfix for you today! There won't be a big beta patch this week, but you can expect the beta content, changes, and fixes to come to the main branch soon.

BUG FIXES

General

Fixed occasional crash when upgrading a card at rest site
Fixed crash that would sometimes occur when entering rooms
When transitioning between rooms, old assets were being freed immediately while the game was still rendering them on screen. This caused rare crashes to desktop, most often when entering events, shops, or campsites. The fix defers the actual freeing to the end of the frame, after rendering is complete.
Fixed an issue with the Game Over screen after discovering multiple enemies while playing in Polish
Fixed rare combat errors that could occur when re-entering combat
Fixed softlock on run histories from older versions of the game
Not Yet card can no longer be generated in combat by effects like Skill Potion
Score is now correct when at Ascension 10

Multiplayer

Colorful Philosophers event can no longer be encountered if a player has only Ironclad unlocked
Fixed curse mismatching when some players would take Neow's Bones relic
Fixed state divergence when Neow's Bones relic would trigger multiple reward screens
Fixed not being able to load into a Daily multiplayer run

Beta Patch Notes - v0.103.0 · Apr 10, 2026

Hey, Slayers! Casey here. This week's beta patch brings two major changes to how scoring works for the Daily Leaderboards!

First and foremost, the leaderboards will now only show your friends' scores. We'll add a way to view global scores later. In general, we don't really want to incorporate invasive anti-cheat protection into the game so it's sort of impossible for us to prevent people putting in the maximum score.

Secondly, no more magic numbers. While there's still points accrued for unlocking new cards and such, the score that's sent to the leaderboards and how it's sorted is based on whether you won, how many badges you accrued, and how quickly you finished the run (in that order). This should clarify why you did better on a Daily run compared to your friends.

Now let's take a look at the rest of the updates, including updated art (like Nonupeipe above), some reworks and balance changes, a new Ironclad card, and new Neow relics (one of which may be very familiar to seasoned Slayers).

CONTENT AND BALANCE

Hey everyone, Anthony here. This week I will be grouping balance and content changes together to better talk about how each section changes overall.

Ancients

Added new Neow relics:
Neow's Bones: "Upon pickup, gain 2 random Neow Relics. Add 1 random Curse to your Deck."
Phial Holster: "Upon pickup, gain 1 potion slot and procure 2 random potions."
Winged Boots: "You may ignore paths when choosing the next rooms to travel to 3 times."

We have three new Neow options you can choose from. I especially like adding more variety to Neow, so we will be looking to expand her set of relics even more over time.

Ironclad

Added new Ironclad card, Not Yet: "Rare - Skill - Cost 2 | Heal 10(13) HP. Exhaust."
Deprecated Grapple card
Changed Colossus card: rarity decreased from Rare -> Uncommon

This set of changes is directly aimed at improving Ironclad's survivability in a big way. Colossus moving to the Uncommon pool helps to lessen the need for Rare defensive options, and should also help Ironclad players that are missing out on Weak. To make room for an Uncommon Colossus, an existing Uncommon had to be cut. Grapple was too low impact (and redundant with Juggernaut) so it made the most sense to cut. Not Yet gives the Ironclad a much needed healing option.

Silent

Changed Acrobatics card: rarity increased from Common -> Uncommon
Reworked Follow Through card: "Uncommon - Attack - Cost 1 | Deal 6(8) damage to ALL enemies. If the last card you played this turn was a Skill, apply 1(2) Weak to ALL enemies." -> "Common - Attack - Cost 1 | Deal 7(9) damage. If you have 5 or more other cards in your Hand, hits an additional time."
Buffed Memento Mori card: base damage increased from 8(10) -> 9(11)
Buffed Speedster card:
Damage increased from 1(2) -> 2
Upgrade changed from +1 damage -> Gains Innate

Acrobatics has consistently been a problem as a Common, completely dominating both win rates and pick rates. When compared to the other cards in its family: Skim, Parse, Glimmer, and Burning Pact, it stood out as the only Common. At Uncommon I expect it to still dominate pick rates, while giving me the breathing room to not overly nerf Sly cards, and in fact maybe even give Silent buffs. I will be watching to see how this change impacts her pool in particular this week. This is still an experiment, so it could be reverted if this change ultimately ends up being worse for the game.

Regent

Changed Regalite relic: now grants Block for any card created, not just Colorless cards

This change makes Regalite consistent with Arsenal, and gives more love to the Regent's Status-generating cards.

Enemies

Deprecated Tunneleing Twosome fight from the Hive
Nerfed Living Fog: no longer increases the amount of bombs it spawns over time
Nerfed Skulking Colony: HP decreased from 74(79) -> 70(75)
Nerfed Byrdonis: HP decreased from 91(99)-94(99) -> 81(90)-84(90)
Nerfed Doormaker:
Overall damage numbers nerfed and moves moved around to better align with the doormaker powers
No longer applies debuffs
Gains less strength

Doormaker maintains his troublesome powers, but gets several changes to make the fight more manageable and feel less oppressive. Additionally, I have started focusing on removing some of the spikiness from Act 1, with the long term plan to shift some of the difficulty from Act 1 -> Act 3. The Skulking Colony change is hopefully the last for a while, as the minor HP adjustment allows killing it one turn earlier at Ascension 8.

ART

Added portrait art for the following cards:
Adaptive Strike
Shadow Shield
Smokestack
Bad Luck
Outbreak
Added new art for Nonupeipe Ancient background
Added new art for the following Neow Ancient relics:
Hefty Tablet
Neow's Talisman
Updated art for Osty in character select screen

USER INTERFACE & EXPERIENCE

Players on the beta branch now submit their scores to a separate beta-only leaderboard
Added a scrollbar to the Run History screen
Badges now show up in Run History screen
Cleaned up the screen when loading a multiplayer Daily Run so that it matches the standard Daily Run screen
Daily Leaderboards now show off floor, badge count, and time instead of score
In multiplayer games, gold score is averaged out across all players to make score uploading consistent for the new schema
Updated Leaderboard view in Game Over screen
Leaderboards shown in the Game Over screen in Dailies now fit better
Your name on the Leaderboards are now highlighted blue so you can more easily find yourself
Reworded Spiraling Whirlpool event to explicitly state that it can only enchant a basic Strike or Defend
Added wrapping navigation to Relic Inventory bar on controller
Big divination button hotkey in Crystal Sphere event no longer uses deck view button on controller

WRITING

Archaic Tooth relic now properly says "Transform a starter card into an Ancient version" instead of "with an Ancient version".
Flak Cannon card description now highlights "Status" in gold
Flanking card now properly specifies that it only doubles attack damage
Iteration, Rocket Punch, and Trash to Treasure card descriptions now say "Status" instead of "Status card"
Pael's Tooth relic now says "Cards devoured" instead of "Cards in the Pot"
Updated translations for various languages
Fixed translation errors for the following languages:
German
Japanese
Russian
Updated credits

BUG FIXES

General

Fixed a blackscreen-at-launch issue related to Steam crashing
Fixed softlock related to opening a secret debug menu
Fixed an issue where, if the player dragged a multi-target attack out of their hand, the damage amount previewed on the attack wouldn't include their Strength if some enemies had Vulnerable while others didn't
"Ascension unlocked" text is no longer displayed in Daily/Custom runs
Fixed leaderboards not being centered properly on non-standard aspect ratios
Fixed cards in hand not being deselected when pressing the top panel hotkey button
Fixed Merchant hand not initially hovering over the first card in the shop when on controller

Beta Patch Notes - v0.102.0 · Apr 3, 2026

Hey Slayers, we've got another Beta patch for you all this week!

Notably, this patch brings in some structural work for a system called Badges.

Badges may appear at the end of a run, noting various things that happened during a run like defeating a boss without losing HP, beating the game quickly, specific easter eggs, or pointing out that you forgot to spend your gold. They're meant as little reminders to let you know what was unique about each adventure.

While they only show up at the end of a run for now, they'll appear in your run history and stats screen later on. This is part of a series of upcoming changes to make runs feel distinct and improve scoring (more on that later!).

In terms of visual changes, there are some new art additions for various cards and a few enemies, as well as some cool new VFX for afflictions!

Up next, we've got some more commentary from Anthony on this patch's content reworks, so let's dive right into it.

CONTENT

General

Reworked Ascension 6 from Gloom - "Less rest sites." -> Inflation - "Removing cards from your deck at the Merchant is more expensive."

As mentioned last week, affecting map generation through Ascension has increasingly seemed to be a miss. It's often too hard to tell what change if any is a result of Ascension, or if it was just an unlucky map generation. Instead Ascension 6 will now make card removal at the Merchant start at 100 Gold, and will increase in price by 50 gold per removal instead of 25. I expect this to be felt significantly more than the old Gloom modifier.

Silent

Reworked Blade of Ink card: "Rare - Cost 1 - Skill | This turn, whenever you play an Attack, gain 2(3) Strength this turn." -> "Rare - Cost 1 - Skill - Add 2(3) Inky Shivs into your Hand."
Added new Inky enchantment: "This card deals 2 additional damage and applies 1 Weak."

The Blade of Ink rework is an experiment with generating Enchanted cards mid combat. Definitely let us know how this feels or if Enchantments are best left to things like Events and Relics. I suspect this card will be high impact, and gives Silent another strong Weak applier.

Necrobinder

Reworked Borrowed Time card: "Uncommon - Cost 0 - Skill | Apply 3 Doom to yourself. Gain 1(2) Energy." -> "Uncommon - Cost 1 - Skill | Gain 4(6) energy. Cards cost an additional energy this turn."

This new Borrowed Time should go particularly well with high cost cards like Reap and Bury and help to flesh out other ways to play Necrobinder.

Enemies

Reworked Doormaker Grasp turn and power: now attacks for 20(23) and the power is reworked to "Whenever you play a card, lose 1 energy."

Doormaker's Grasp turn was too underwhelming, and overall lowered the difficulty of the fight too much. This new version should make the entire fight high stakes and actually give the player a difficult problem to puzzle over turn to turn instead of making the fight about just living until turn 4.

BALANCE

Silent

Buffed Leading Strike:
Shivs increased from 1 -> 2
Damage decreased from 7 -> 3
Nerfed Speedster: damage decreased from 2(3) -> 1(2)
Nerfed Untouchable: Block decreased from 7(9) -> 6(8)

Potions & Relics

Changed History Course relic: when it plays a copy of an X-cost card, it now uses your current energy for its X-value instead of the energy spent the last time the card was played. Note: It still plays the copy for free

Enemies

Buffed Skulking Colony:
Now attacks on all turns
Deals slightly more damage

Ancients

Buffed Nonupeipe's Fur Coat relic: now affects restocked Axebots and other enemies that enter combat during a fight

Events

Nerfed Hungry For Mushrooms event: Fragrant Mushroom option upgraded cards decreased from 3 -> 2
Changed Waterlogged Scriptorium event:
Prickly Sponge option gold cost lowered from 155 -> 99
Tentacle Quill gold cost lowered from 65 -> 55
Buffed Whispering Hollow event: Exchange option gold cost decreased from 50 -> 35+-9

ART

Added portrait art for the following cards:
Hotfix
Modded
Synthesis
Sweeping Gaze
Added new art for Ruby Raiders
Added background art and VFX for Vantom boss fight
Added new visuals for the following afflictions:
Bound
Entangled
Galvanized
Hexed
Ringing
Smog
Updated empty chest VFX, smoke puffs

USER INTERFACE & EXPERIENCE

General

Players can now navigate to the top bar character portrait to see the Ascension hovertip on controller

Multiplayer

Better handling of intermittent Steam errors
Disabled skipping chests in multiplayer. Too many people thought it was the Proceed button.

WRITING

General

Foul Potion description now specifies that it deals damage to "ALL players and enemies" instead of "EVERYONE", making it clearer that it does not hit Osty

Localization

Japanese
Italian
Spanish
Thai

Beta Patch Notes - v0.101.0 · Mar 27, 2026

Hey everyone, Anthony here. It's time for another Beta Patch where we test out experimental changes. Today we are going to do something a little different for the patch notes as I will be giving some insights into our design intent and thoughts behind various changes. Reminder that nothing in the beta branch is set in stone, expect lots of back and forth, and above all please let me know what you think by using the in-game feedback tool by hitting F2! I read countless pieces of player feedback and it has been instrumental in helping guide our process.

Reworks and Reverts

Silent

Deprecated Prepare and Prepared returns: "Common - Skill - Cost 1 - "Discard 2 cards. Next turn, gain 2(3) Energy." -> "Common - Skill - Cost 0 - Draw 1(2) card(s). Discard 1(2) card(s)."

Necrobinder

Reverted (Buffed) Capture Spirit to its previous version: "Uncommon - Skill - Cost 1 - Enemy loses 2(3) HP. Add 2(3) Souls into your Draw Pile." -> "Uncommon - Skill - 1 - Enemy loses 3(4) HP. Add 3(4) Souls into your Draw Pile."
Reverted (Buffed) Borrowed Time to its previous version: "Uncommon - Skill - Cost 0 - Apply 6(3) Doom to yourself. Gain 1 Energy." -> "Uncommon - Skill - Cost 0 - Apply 3 Doom to yourself. Gain 1(2) Energy."

Starting off, I am reverting the changes made last week to Prepared, Borrowed Time, and Capture Spirit. For Prepared, while I still think that the Sly synergies are overall too dominant of a strategy, Prepared is so integral to the Silent's core identity that I will be looking for a different approach to bring Sly in line in the future. Borrowed Time is likely to receive a complete rework in the future, but for now I prefer that the card is fun to play with in all decks.

Regent

Reworked Arsenal card: "Power - Rare - Cost 1 Whenever you play a Colorless Card, gain 1(2) Strength." -> "Power - Rare - Cost 1 (Innate.) Whenever you create a card, gain 1 Strength."

Potions & Relics

Reworked Pendulum relic: "Common - Whenever you shuffle your Draw Pile, draw a card." -> "Common - Every 3 turns, draw 1 card."

Enemies

Reworked and nerfed the Doormaker. Fight is now less random.

Doormaker is receiving another rework! Now each visual phase he is in has its own unique power to hamper the player. All of them are disruptive and will hopefully encourage interesting play, but should now be less random and reward player agency more.

BALANCE

General

Elites can no longer spawn on floor 6 to better match StS1
Improved map generation consistency
Fixed maps sometimes generating with fewer shops than intended
Gloom Ascension modifier no longer affects ? rooms in addition to Rest Sites

Since Neow now counts as the first floor of the map, Elites were actually spawning one floor earlier than they should have been. This change should have a big impact on how tough fighting early Elites is. Additionally we found some improvements could be made to the map generation algorithm to help limit the number of maps overflowing with early monster rooms and not much else. For the Gloom change, although it did make the game more difficult it was not in a satisfying or fun way as it just made maps less interesting. Instead I will be looking to rework Gloom entirely in the future to a modifier that makes the game harder but in a more interesting way.

Ironclad

Buffed Cinder card: now Exhausts a random card in your Hand instead of the top card of the Draw Pile
Changed Tremble card: now Exhausts

Tremble gaining Exhaust is a buff to Ironclad's Exhaust synergies, and coupled with the Cinder change should have a large impact on the Ironclad's cardpool.

Silent

Buffed Serpent Form: Damage increased from 4(5) -> 4(6)

Regent

Buffed Falling Star card: Damage increased from 7(11) -> 8(12)
Buffed Glitterstream card: Next Turn Block increased from 4(6) -> 5(7)
Buffed Parry card: Block gain increased from 8(11) -> 10(14)
Buffed Refine Blade card: Forge increased from 6(10) -> 9(13)
Buffed Celestial Might card: Upgrade changed from +2 damage -> 1 additional hit
Buffed Guiding Star card: now draws cards immediately instead of next turn
Buffed Sword Sage card: no longer increases the cost of Sovereign Blade
Changed Spoils of War card: now draws 2 cards, but Forge decreased from 12(17) -> 5(8)

Defect

Nerfed Voltaic card: Energy cost increased from 2 -> 3

Potions & Relics

Buffed Tiny Mailbox relic:
Rarity moved from Common -> Uncommon
Potions procured increased from 1 -> 2
Changed Permafrost relic: Rarity moved from Common -> Uncommon
Changed Bag of Marbles relic: Rarity moved from Uncommon -> Common
Changed Red Mask rarity relic: Rarity moved from Uncommon -> Common
Changed Bellows relic: Rarity moved from Uncommon -> Rare
Changed Lasting Candy relic: Rarity moved from Rare -> Uncommon
Changed Crossbow Tanx relic: Now uses Free to Play instead of Costs 0 Energy
Changed Vexing Puzzlebox relic: Now uses Free to Play instead of Costs 0 Energy (Now also only lasts until end of turn)
Changed Liquid Memories potion: Now uses Free to Play instead of Costs 0 Energy

For relic rarity, the design goal is that commons are not necessarily weaker, but that they are often simple effects that could add value to most decks. As rarity increases we allow higher complexity and more impact on drafting/play decisions.

Enemies

Nerfed Skulking Colony: deals less damage, damage scales slower, and no longer applies Dazed status cards
Changed Haunted Ship: now applies Dazed status cards to the player
Nerfed The Lost and Forgotten: stat theft no longer scales with Ascension
Nerfed Waterfall Giant: HP decreased from 250(260) -> 240(250)

Skulking Colony went from too weak to too strong. This nerf should put his encounter more in line with how difficult the fight was intended to be. Additionally I found that the Dazed statuses actually worked against the design goals of his power, the new version is a tighter design overall that presents a more unified question for the player to answer. If the encounter is now too weak, simple numbers can be buffed in the future.

Events

Disallowed Gold generating relics from showing up as the featured relic in the Welcome to Wongo's event
Mad Science Skill Chaos option (In the Tinker Time event) now uses Free to Play instead of Costs 0 Energy

ART

Added Test Subject burn animation
Axe and Crossbow Ruby Raiders now have improved textures
Added Portrait art for the following cards:
Compact
Shatter
Fuel
Consuming Shadow
Subroutine
Trash to Treasure

USER INTERFACE & EXPERIENCE

Date at top-right now reflects build date instead of current date
Increased feedback form character limit from 500 to 8000

Receiving in-game feedback from YOU the player is the best way we have of improving the game. Many of you have requested the ability to write more without hitting the character cap too early. We've increased the character count 16 fold, so I am eagerly looking forward to reading your effort posts!

BUG FIXES

General

Fixed exploit where you could controller navigate to card grid when the upgrade/remove/enchant/transform preview screen is open
Fixed a crash that could occur at the start of the player's turn when abandoning a run

Reworked mod structure

PCK is no longer required for all mods. Json is the only file that is required to declare a mod. The json must declare whether the mod includes a pck/dll file.[/*]
settings.save now includes a list of all mods that were loaded in the last game run. Reordering this list affects load order.[/*]
Mods may declare dependencies in the manifest. If settings.save declares a load order incompatible with the listed dependencies, then a re-sort is forced.[/*]
Added affects_gameplay field to mod manifest. If false, then the mod will not be checked against the host's mods in a multiplayer game.[/*]
Updated 0Harmony/MonoMod to support mac arm64. Manually overwriting it should no longer be required.[/*]
