Preternatural Turn with crystals:
- If the boss is doing a pointblank AoE, the crystals will do wide conal AoEs toward the outside of the arena. The safe spots are between the farthest crystal and an adjacent one, a bit closer to the far one and outside of the pointblank
- If the boss is doing a donut AoE, the crystals will do pointblank AoEs. The safe spot is a small triangle just inside the inner circle of the boss's hitbox toward the far crystal
- Unei can provide all the heals you need as long as you don't get hit by anything avoidable
- A Doga demiclone will defeat the boss in about 10m15s with no player assistance
