Highlord Omokk

Lower Spire: ogres and trolls
Take the Lower Spire descent rather than the locked upper doorway. Cross the bridges into the ogre quarter for Highlord Omokk, then continue through the troll rooms to Shadow Hunter Vosh'gajin and War Master Voone. Pull bridge packs onto a cleared platform, and finish each caster pack before advancing into the next room.

Highlord Omokk
Elite HumanoidOmokk tests whether the tank can hold a wall-backed position through Knock Away and survive the increased melee pressure of Enrage.
Abilities

Knock Away
Inflicts normal damage plus 30 to an enemy and knocks it back.
Put the tank's back against a wall so Knock Away cannot launch them off the fighting platform, then settle Omokk before melee players close in again.

Enrage
Reserve tank mitigation and finishing damage for Enrage instead of relying on a health threshold to predict it.
Tank- Set your back against the ogre platform's wall before engaging. Re-establish that position after Knock Away and use mitigation when Enrage appears.
Healer- Keep the tank in range after Knock Away and have a strong heal ready for the faster melee hits during Enrage.
Damage- Leave the wall-backed position to the tank, pause if Knock Away sends Omokk toward you, and save a damage cooldown to shorten Enrage.
