The Secret Post-Game Boss In Labyrinth Of Refrain: Coven of Dusk

Labyrinth of Refrain: Coven of Dusk is a meaty dungeon-crawling soiree, with players forging superior gear and characters over many hours of synthesis and combination. The final battle, accessible only after completing a lengthy secret dungeon and completing the main game with the six black pages obtained from other huge (and sometimes difficult to find) bosses, can be an extremely difficult encounter. The boss has abilities that can easily one shot even the hardiest characters, with a host of debuffs and other powerful attacks.
