Requires careful planning to upgrade every card before the final boss.
Strategy Tips
Focus on small deck sizes to make upgrading every card feasible. Rest sites and upgrade events are your best friends. Cards like Armaments (from STS1 equivalent mechanics) that upgrade all cards in hand can accelerate progress dramatically.
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.
