Hall of Illusions (Hard) — Boss Mechanics

Frontal cleaves plus a periodic room-wide shockwave that must be dodged by timing. The Hard-version timer is unforgiving: kill adds in a fixed order or the shockwave windows overlap and one-shot the raid. Assign one ranged player to bait the cleave away from the stack.

Barrier phases: the boss becomes damage-immune behind barrier walls and spawns mirror illusions. Break the glowing barrier — attacking mirrored barriers reflects damage onto the party on Hard. Save burst stigmas for the vulnerability window after each barrier falls.

Final boss: enrage timer + choir summons. Keep the summon adds controlled — their combined beam debuff stacks lethal damage on the tank. Hard mode adds a second enrage window at 30%; hold long-cooldown burst for that phase and keep sustained healing through the last 10% of HP.
