Phase 1 (Diamond)

Phase 1 (Diamond) features two distinct timeline variations depending on the sequence of mechanics chosen by the boss. Both variations share an identical opening sequence through the initial Grim Embrace debuffs and wall Lasers, after which the fight branches into Variation 1 or Variation 2 before transitioning into Phase 2.

Upon completing Phase 2, the encounter returns to Phase 1 to execute the opposite variation before casting a final Deluge of Darkness enrage. Note that on unsynced runs, parties typically defeat the boss during the transition and will skip this repeat phase entirely.

Throughout Phase 1, the boss performs 24 auto-attacks that inflict a stackable Lightning Resistance Down debuff on her target.

• Aggro Priority: All tanks must have tank stance enabled. The main tank opens with Provoke at the start of the phase to secure initial aggro.
• Tank Swap: Tanks must swap aggro at 6 stacks of Lightning Resistance Down to prevent lethal damage from combined mechanics and auto-attacks.

The boss tethers 12 random players first, then the remaining 12 players, applying delayed hand debuffs. The boss's hand motion indicates the direction of the AoE upon expiry.

• Grim Embrace (Forward): The slap AoE will spawn behind you. Move forward / away from your back.
• Grim Embrace (Backward): The slap AoE will spawn in front of you. Move backward / away from your front.
• Getting hit by a hand AoE inflicts a 25% Damage Down stack and Doom (cleansable with Esuna).
• A countdown timer (5 to 0) appears above your character right before expiry, accompanied by a Heavy movement slow.
• Always resolve your debuff at the outer edge of the arena with the hand pointed outwards!

The boss summons two sets of 5 Cloudlets along the arena walls that fire straight-line lasers in alternating sets of 2 and 3 per side.

• Identify a tile that is safe from the 1st laser set, but adjacent to a tile currently being targeted by the 1st set.
• Immediately after the 1st laser set fires, step onto the freshly cleared tile to safely dodge the 2nd laser set.

• Flares: Proximity AoEs. 3 designated players run to their assigned alliance corners. All non-marked players stack tightly under the boss.
• Unholy Darkness: 4-man stack AoE on each healer. Position Healer 1 close to the boss and Healer 2 behind. Do not overlap stacks.

The boss fires four sets of three laser beams dealing heavy raidwide damage.

• Preposition in designated alliance lines.
• Tanks in front: The first two players hit take extra damage, so tanks must stand in front to soak for the party.
• Stay in your group until the mechanic concludes.

The boss and 2 Sinister Eyes channel a petrifying gaze.

• Turn your character's facing direction away from the boss and both Sinister Eyes before the cast completes.
• Failure results in Petrify.

• Enaero (Aero): Massive middle knockback. Use Arm's Length / Surecast and stay out of the center blue killzone.
• Enddeath (Death): Massive middle pull. Use Arm's Length / Surecast and stay close enough to step in after the initial proximity hit.
