Moon-Maddened Callis starts with an armor bar, which takes increased damage from Corrosive weapons. Once the armor is broken, her second bar is flesh, which is highly vulnerable to Incendiary damage.
Moon-Maddened Callis unleashes fire waves that travel across the arena and deal heavy damage on contact. Time your jumps to avoid taking damage.
After depleting her armor, Moon-Maddened Callis becomes immune to damage and will summon red constructs that slow and damage you if touched. Use this time to clear out enemies to prevent you from getting overwhelmed once she becomes vulnerable again.
