Mahkteah Boss Fight Strategy

Beat Mahkteah The Corrupted Seraph in Crimson Moon: phase 1 and 2 attack timings, parry windows, stagger counters, and boss drop rewards.

QuickAnswer / Tactical Key Finding

Defeating Mahkteah, The Corrupted Seraph requires parrying his telegraphed two-handed Abyssal Cleave in Phase 1, sprinting outside his red Eclipse Nova arena radius at 75% HP, and staggering his wing cores during Phase 2 with Greatsword heavy attacks.

Act 1 Climax: Mahkteah, The Corrupted Seraph

Guarding the grand threshold to the Sunken Cathedral, Mahkteah stands as the first true skill-check boss in Crimson Moon. Once a revered angelic commander of Gildenarch, Mahkteah has been consumed by the crimson eclipse, wielding a massive obsidian blade and dark feathered wings that sweep the arena.

Accompanied by a driving metal soundtrack composed in collaboration with guitarist Jared Dines, this two-phase encounter demands precision parrying, awareness of ground markers, and coordinated stagger bursts.

Phase-by-Phase Battle Strategy

Phase 1: The Fallen Commander (100% - 75% Health)

During the opening phase, Mahkteah tests your mastery of basic combat fundamentals. Stay at mid-range to bait his three-hit ground combo. The first two horizontal sweeps can be parried comfortably. Parrying the final overhead smash immediately puts Mahkteah into a mini-stagger, granting you ample time to land a charged heavy strike.

If he leaps into the air for the feather volley, do not attempt to parry. Instead, sprint in a circular arc around the arena edge until he slams back down, then close the distance with a dashing light strike.

Phase 2: Demonic Ascendance (75% - 0% Health)

At 75% health, a cinematic sound cue plays as Mahkteah plunges his sword into the ground, initiating the Eclipse Nova. Retreat to the outer arena perimeter immediately.

In this heightened state, Mahkteah gains void-infused aerial dashes and increased attack speed:

  1. Target the Wings: Focus your heavy attacks on his glowing wing joints to deplete his posture bar rapidly. Breaking both wings downs him for 6 seconds, opening up a full visceral execution prompt.
  2. Trigger Angel Mode: When his health drops below 30%, activate your 20-second Angel Mode transformation to deliver overwhelming radiant damage before his rage phase overwhelms your stamina.
  • Primary Armament: Radiant Cleaver Greatsword (+2 minimum) for maximum poise reduction, or Seraph Talon Daggers with Holy Paper buff.
  • Relic Slots: Equip the Ring of Holy Vigor for accelerated stamina regeneration and the Martyr’s Crest to widen your parry window by 4 frames.
  • Flask Allocation: Ensure Sister Veronica has upgraded your Sanctuary Flask to at least 3 charges before initiating the boss gate.
