Mega Crit has released a new beta patch for Slay the Spire 2 that replaces the Act 3 boss Doormaker with Aeonglass and adds a Bestiary feature.
The update, available now to beta branch players, also includes numerous balance changes and bug fixes. In the patch notes, the developer explained that Doormaker exceeded desired complexity levels. The team chose to start fresh with Aeonglass to better match intended goals for the encounter.
