Loadout

Fill inventory before the arena. Use everything — Mission II ends here.

  • Throwing knives — chip without melee trades.
  • Health potions — as many as you carry.
  • Damage buffs — pop before engage if you have them.

Keep one potion for phase two.

Attack patterns

Attack Telegraph Dodge Punish
Horizontal slash Weapon to side Roll through swing 1–2 hits
Overhead smash Weapon overhead Roll sideways (not back) 2–3 hits, back off

Overhead has small AoE on impact — sideways only.

Fight flow

  1. Open with 2–3 knives while he walks in.
  2. Maintain ~two rolls of distance.
  3. Bait swings, dodge, punish short — don't get greedy.
  4. Angelic Ascension after a heavy dodge, sub-50% HP — burst melee or knife flurry.
  5. Die once? Second attempt at the checkpoint — learn patterns first run, go all-in second.
