Purity
BossPurity is the 4th story boss inside Fairy King Forest, an ancient forest ruled by fairies and armored demons. It caps a 15-wave act that opens with 8x Fairy, 8x Knight in wave 1 and scales up to a final wave of 9x Fairy, 14x Knight, 3x Red Demon (Elite), and Purity itself. Its health pool and aggression sit noticeably above the Basic and Elite spawns that lead up to it.
Enemies in this act can carry the Armored, Tank, Commander, Stunner modifiers: Armored (shrugs off a flat 33% of incoming damage); Tank (trades speed for a larger health pool); Commander (buffs every enemy near it, making it worth focusing down early); Stunner (periodically stuns nearby placed units for several seconds).
Compared to Act 5's closing boss Piety, Purity is an earlier, more approachable check in Fairy King Forest's Story campaign, though it still requires a full 15-wave clear rather than a solo encounter.

Where Purity Appears

How to Counter Purity
Since Purity's wave carries the Armored, Tank, Commander, Stunner modifiers (Armored (shrugs off a flat 33% of incoming damage); Tank (trades speed for a larger health pool); Commander (buffs every enemy near it, making it worth focusing down early); Stunner (periodically stuns nearby placed units for several seconds)), building a team that can handle those effects matters as much as raw damage against Purity itself.
