Slay the Spire 2 Beta Hotfix Notes - v0.105.1 (9th May 2026)
A targeted hotfix lands for Slay the Spire 2, cleaning up Aeonglass issues and several multiplayer desync problems introduced in yesterday's big update.
Less than 24 hours after Aeonglass replaced the scrapped Doormaker as Slay the Spire 2's new Act 3 boss, Mega Crit has pushed v0.105.1 to clean up a handful of bugs that came along for the ride.
The most noticeable fix is Aeonglass showing a buff icon on its first move intent when it should have been displaying a debuff. In a game where reading enemy intent correctly can decide a run, that's not a cosmetic issue, it's actively misleading. Music bugs for both Aeonglass and the Ceremonial Beast are also patched, which matters more than it sounds since audio cues in Slay the Spire 2 carry real gameplay information. On the multiplayer side, the Silken Tress relic was only applying card reward bonuses to the host rather than all players, and two separate state divergence bugs tied to treasure rooms and the Crystal Sphere event have been resolved.
Small patch, but the right one to ship fast. Here's the full breakdown.
