WoW Kith'ix Raid Guide: Unbinding of Kith'ix Strategy and Loot

Quick summary

• The Unbinding of Kith'ix is a single-boss raid added in patch 12.1.5. It sits beneath the Venomous Abyss, and you fight Kith'ix alongside Lady Liadrin. Mythic is a flexible 15–25 players (Blizzard).
• Kith'ix drops 285 / 298 / 311 / 324 gear on Raid Finder / Normal / Heroic / Mythic, all starting at 3/6 on their tracks (Wowhead).
• Phase 1: kill the adds before Kith'ix reaches 100 energy, keep them away from him, and grab Liadrin's Light's Embrace before each Extinguish. Phase 2 starts at 25% health and is a burn: Liadrin's Luminous Grace doubles damage and healing, and you have to finish before the eighth Eclipse.
• No tier set drops. Instead you get four cantrip armor pieces, two swords, three role trinkets, a ring, a hearthstone, a decor item, and on Mythic only, a Paladin glyph libram.
• The kill counts toward the Great Vault raid row.

Wowhead warns that the path to the entrance is "littered with enemies," so travel as a group.

Know the rules before you pull

Wowhead lists three rules that decide the fight:

Rule	What it means	Source
Commanding Presence	Adds near Kith'ix take 50% less damage, so keep him away from them	Wowhead
All adds dead before the intermission	Survivors get Dark Frenzy: +100% attack and movement speed, crowd-control immunity, and raid damage	Wowhead
Exhausted (soft enrage)	Each Divine Radiance weakens Liadrin's help and raises Suffocating Darkness damage by 10%	Wowhead
Eightfold Eclipse (hard enrage)	When the eighth Eclipse lands, the raid dies	Wowhead

Wowhead's notes: Bloodlust in Phase 2, no interrupt assignments, and dispel Overwhelming Fear.

Clear Phase 1: Darkness' Domain

1. Voidswarm. Kith'ix channels for 6 seconds, dealing raid damage and summoning adds (Wowhead).
2. Handle the adds. One tank holds Kith'ix at the edge of the area. The other tanks the Venomous Hulk on top of the Voidweaver so both can be cleaved. Face the Hulk's Venom Roar cone away from the raid. Bomber Beetles chase players and explode on contact or after 30 seconds, putting a stacking Digestive Juices DoT on the whole raid, so stagger the explosions.
3. Unspeakable Horrors. If you get a purple arrow, run out within 6 seconds. Healers dispel the fear once you're clear of the group, because the scream does damage based on distance.
4. Extinguish. Liadrin scatters balls of light. Every player runs through one to get Light's Embrace (90% less Shadow damage for up to 8 seconds) before Kith'ix's shockwave lands.
5. Twisted Appendage. Tentacles slam the ground 3 seconds after their circles appear. Step out.
6. Tank swap. Swap on 1 stack of Dark Devastation. It leaves the target Devastated (+150% Physical and Shadow damage taken for 25 seconds), so carry the circle away from the raid.

Example: At about 80 energy, call for the last Voidweaver to die. Any add still alive at 100 energy gets Dark Frenzy and starts damaging the whole raid during the intermission.

Survive the intermission

When Kith'ix reaches 100 energy, Suffocating Darkness closes in on the room. Stand in Liadrin's Refulgent Bulwark while the Phase 1 mechanics continue. No new adds spawn. Abyssal Grasp puts a heal absorb on random players, and anyone who isn't healed through it within 8 seconds gets dragged into the darkness. Drop your Dark Devastation circle near the edge of the bubble without stepping outside. When Liadrin reaches 100 energy, Divine Radiance clears the darkness and stuns Kith'ix for 8 seconds (Wowhead).

Heroic and Mythic only: each Dark Devastation leaves a pool. During the darkness, these pools release Eclipse Fragments that drift toward Liadrin. Players spread out and intercept them, taking a small stacking DoT. Any fragment that reaches Liadrin triggers Lost Refulgence: raid-wide stacking damage and a smaller bubble.

Burn Phase 2: Last Light

At 25% health, Kith'ix stuns everyone with Stygian Howl and absorbs his remaining adds. Liadrin casts Last Light, a full heal that grants Luminous Grace (+100% damage and healing). Use Bloodlust and your cooldowns here (Wowhead).

• Eightfold Eclipse: each Eclipse hits the raid. When the final one lands on Liadrin, everyone dies.
• Null Gate: spread out once the gate drops. Nullshards scatter from it, and each hit adds a stack of Nullify.
• Negation (tank): swap on it. Running through a Null Gate removes the debuff and destroys the gate, but it explodes around the tank, so give them room. On Mythic it applies multiple stacks.

Collectibles: Shadeweaver's Hearthstone, Kith'ix's Seal (housing decor), and the Libram of the Matriarch, which is Mythic only. The libram teaches Glyph of the Matriarch's Wings, which gives Avenging Wrath Liadrin's wings (Wowhead).

Return or bring an alt

• Returning player: Raid Finder and Normal are where to learn the fight. Wowhead hasn't published the Raid Finder item level requirement yet.
• Alts: a one-boss raid is a quick way to fill a Vault slot. From October 20, the crest cap is lifted (Blizzard).
• Achievement hunters: Wowhead lists Normal, Heroic, and Mythic kill achievements, plus guild-run versions. Track them on our achievements hub.
