arch demon piece
Enemy pieces
Signature: Abyssal Swing
Weaknesses come straight from the game data (they match the in-game board preview). The star ratings the preview shows for Strength / Intelligence / resistances aren't decoded yet, and attack patterns beyond the signature action aren't in the data at all — that's what the write-up below is for.
Strategy
Mechanics
Arch demon piece.
- Abyssal Charge — spawns lances that fire line AoEs.
- Dismember — blue floor lines; dodge into the safe zone once the first set goes off.
- Abyssal Transfixion — spawns daggers / crosses that explode into circular AoEs.
- Axe attack — frontal half-room cleave. Stay in the back half of the hitbox.

Abilities & loadout
Arch Demon Piece — standard enemy.
Suggested trio: Coeurl, Geshunpest, Behemoth — Lightning damage and bulk.
Abilities
- Abyssal Charge — spears around the arena fire lines at you
- Dismember — five lines sweeping east→west or west→east, one at a time
- Abyssal Transfixion — swords drop circles beneath them; an axe cleaves in front of the boss
How to handle it
Move out of the Abyssal Charge lines. For Dismember stand in the middle and step into a square that has already gone off — the timing is trickier than it looks. Move away from the hanging swords, then get behind the boss for the axe cleave.
It loops and starts layering mechanics, so burn it before that gets messy.
