Boss Guides

The fight that made everyone uninstall. Three phases, an aggro meter that explodes if you ignore it, and catapults that arrive the moment you think you're winning.

A patrol-based boss that punishes static tower placement. His route changes each phase and a wall breach sequence forces emergency repositioning mid-fight.

One-shots clustered towers with spike attacks. Every phase tightens the safe zone. You need spread positioning and fast burst windows before the spikes reset.

Immune to physical damage while the Hollow Aura is active. Standard tower DPS does nothing in Phase 2. You need items that bypass armour or the fight never ends.

Maximum armour makes this fight a war of attrition. Siege engines deal AoE damage every 12s, and avalanche events wipe unprepared formations on the mountain path.

Suppresses your items in Phase 3, turning your best gear off. Tower curse stacks across all four zones. The hardest fight in the game — and the key to Endless Mode unlock.
