Slay the Spire 2 Beta Patch Notes - v0.105.0 (8th May 2026)

Doormaker is out, Aeonglass is in, and the Bestiary has arrived, here's everything in Slay the Spire 2's latest beta patch.

The biggest headline in v0.105.0 is Doormaker getting scrapped entirely. MegaCrit decided the Act 3 boss was too mechanically complex for what they actually want from that slot, so rather than keep patching around the edges, they've replaced him wholesale with a new boss called Aeonglass. That's a bold call this early in Early Access, and I respect it more than watching a problem boss limp along for months.

Also new this patch is the Bestiary, now accessible through the Compendium. It's still early, monster data isn't fully implemented yet, but being able to browse enemy animations and stats in a dedicated screen is a solid addition. On the balance side, the Defect gets a meaningful round of buffs, with Shatter now evoking all orbs twice and Hyperbeam's damage bumped up, while the Regent sees Sword Sage reworked around a Replay mechanic that opens up new synergies with Parry.

MegaCrit has also confirmed a shift to bi-weekly patches going forward, which should give beta players more time to stress-test changes before they hit the main branch. Everything in the update is listed below.

Full Patch Notes

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.
