Quick Answer

Mission IV: Ancient Chamber after M I–III on second run. Grab boon (stamina/poison). Heal below 50%. Co-op: designate reviver. Red Abrais stone.

Second full run Mission IV world boss — Mahkteah, The Lord of Perdition. You've already taken E'Efrae on run one — this is the marathon, not a speedrun.

Mahkteah, The Lord of Perdition — Mission IV: Ancient Chamber

Before the fight

  1. Replay Missions I–III — stock heals and damage consumables. Clear nexus gates for extra loot.
  2. Grab the extra boon before Mission IV: World Boss — Ancient Chamber — non-negotiable in my route:
Boon When I pick it
Light attack supply poison Steady DoT on big HP pool
Stamina recovery Solo — more dodges
Poison bonus Already on poison build

Fight flow

  1. Few light attacks to read pattern, then back off.
  2. Dodge through telegraphed heavies — don't block everything. One heavy swing can take ~⅓ HP.
  3. Heal below 50% — don't wait for one-shot range.
  4. No long combos — counterattack stagger hurts.

Co-op

  • One player draws aggro, one DPS.
  • Teammate revive doesn't cost your heal charges — designate who revives.
  • Solo = no safety net; near-perfect dodges or bust.

Reward

Red Abrais stone — essential for final run. Miss it and you redo the full second run.
