Fight Mechanics by Phase
P1 (100%–66%)
Barrier absorbs magic damage. Physical classes carry; casters should focus on the Resonant Echo adds.
P2 (66%–33%)
Barrier flips to absorb physical damage. Roles swap — this is where single-damage-type parties stall out.
P3 (33%–0%)
Barrier drops but the boss gains +50% attack speed. Burn defensives and finish before the enrage timer.
