Tuten'kash

The Caller's Chamber
Work through the entrance packs to the gong chamber. Check the concealed pack on the left before engaging the right side. Clear the chamber, then defeat each gong wave before ringing again: Tomb Fiends come before Tomb Reavers, followed by Tuten'kash.
Tuten'kash
Elite UndeadTuten'kash tests whether the group keeps the healer out of Web Spray while clearing the curse and poison left by the gong encounter.
Abilities

Web Spray
Immobilizes enemies in a cone in front of the caster for 10 seconds.
Keep everyone except the tank behind Tuten'kash; Web Spray immobilizes enemies in front of him.

Curse of Tuten'kash
Reduces the casting speed of nearby enemies by 15%, and increases the time between their attacks by 18%. Lasts 15 minutes.
Remove the curse from the healer promptly, then clear it from the other affected players before continuing. It slows casting and attacks rather than dealing direct damage.

Virulent Poison
Remove Virulent Poison when its continuing Nature damage competes with tank healing; its damage continues between melee hits.
Tank- Keep Tuten'kash's Web Spray aimed into cleared space rather than through the group. Call for curse removal if its attack slowdown makes it difficult to hold him.
Healer- Stand behind Tuten'kash so Web Spray does not pin you in place when you need to move. Ask for the curse to be removed from you promptly, and account for Virulent Poison continuing to hurt its target between attacks.
Damage- Attack from behind to avoid Web Spray. Curse removers should free the healer from Curse of Tuten'kash first and clear the remaining curses before the next pull. Remove poison if your class can do so.
