Read the encounter
A masked alchemist firing fast reagent bolts between tightly spaced pool detonations and broad flame cones. Keep moving across the pool sequence, then circle behind the committed cone. Below half health, five pools ignite in quick succession and cones gain a delayed impact. Mixing pauses are very short.
Keep moving during the warning, then use the recovery window to position your spinning yo-yo. Cast only when your weapon’s allowed state and spell cooldown permit it.
Bosses reposition between attacks and during attack warnings, and try to leave active spinning yo-yo circles, including extra Hat Trick yo-yos. Lead their movement with your throws, then aim at their marked ground hazards and use stagger windows to hold spin damage on them. Normal enemies still stop to attack. Walls, movement slows and overlapping circles can limit their escape.

Loot and signature weapon
Base guaranteed resources start at 50 coins and 4 relics, with a random bonus of 0–12 coins and 0–1 relic. An additional weighted roll uses these current outcomes:
| Chance | Outcome |
|---|---|
| 25% | Alembic Coil |
| 42% | 10 additional coins + 3 additional relics |
| 33% | 45 additional coins + 0 additional relics |
A separate 25% armor roll can award one of the four pieces in this boss’s set. Weapon and armor rolls are independent. Difficulty changes quality, while current drop chances remain the same. Collect floor drops and extract to bank them; difficulty scales currency rewards.
