·Multi-source verified (83/83)

The Act 3 bosses are the final challenge before the Spire's true ending. They are incredibly powerful and demand a highly optimized deck. The Awakened One gains Strength when you play Powers. Donu and Deca require balanced damage to avoid over-buffing one. The Time Eater punishes playing too many cards. Each boss requires a specific approach and a deck capable of adapting to their unique mechanics. Prepare for long, intense battles.
