Weakness
No damage weakness — the fight is pure survival. Bring full healing and play the long game; his phases run a fixed, learnable pattern set. (Community-sourced.)
SPARE route
Spare by ACTing nearly every turn to wear him down over many rounds, then SPARE — it’s the repeated ACT, not damage, that frees him. (Exact ACT names are community-reported.)
Tactics
Two payoffs: SPARE for the Jevilstail armour, or FIGHT to 0 (~3500 HP) for Susie’s Devilsknife. Either way it’s an endurance test — memorise the cycles and keep everyone healed.
Recommended setup
- Full healing stock
- Best available Ch1 armour
S-rank / no-hit
His attack order is deterministic (no RNG), so a no-hit run is pure pattern memorisation.
