Swing: he swings his club down and across the room, towards the player.
Great Combustion: when the player is directly in front of him, he will cast Great Combustion. This spell is very fast.
Flame Breath: he spews fire outwards from his mouth in a cone-like shape, moving the stream towards the player until he finishes.
Summon Meteors: Starts waving club in the air. Five seconds later, meteors will begin to fall and drift towards the player's location.
Flame Wave: he knocks the base of his club on the ground several times. During the last two or three knocks a small bit of flame appears in a circle a short distance from him, becomes lava-like and moves towards his center then goes back out.
Once below 20% health, he will stop attacking and collapse slightly. After 5 seconds he will emit a massive fiery shockwave, dealing heavy damage if the player is within the shockwave.
Collapse: he will collapse further, dealing minor damage in a shockwave around him.
- As the boss has no catch-up mechanics like a jump or a charge, you can kill him with a bow relatively trivially without getting hit.
- His breath attack works similarly to that of The Old Iron King. If you have under 30% equip load you can roll through it easily, but any higher and you risk taking damage unless your roll is perfect.
- It is possible to glitch the boss, by staying in the doorway. He will get stuck in the wall, use ranged attack to kill.
