Compendium

Bosses

Each act boss wears a Seal of the Lastlight Road: Grukk the Earth Warden's crown, Morvaine the Seal of Bone, Old Gutrot the Seal of Water and Seraphel the Seal of Light, while Vhoruun burns under the last, Ash. Stats are at monster level 1; the game scales them with the dungeon's level, Pyre Tier and party size. The five act bosses fight in rounds: adds, then a move only you can answer, then a window where they take full damage. Other bosses' specials change as they pass their phase thresholds.
