About Mastery Achievements
Mastery achievements represent the pinnacle of Slay the Spire 2 skill. These demand exceptional deck-building, creative strategies, and often self-imposed restrictions that push even veteran players.
Note: Slay the Spire 2 is currently in Early Access. Steam achievements are not yet available but may be added in a future update. These in-game achievements are tracked within the game itself.
