Slay the Spire 2 Patch Notes — June 4, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
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....

...Like this new Defect animation!
Without further ado, let's dive in...
