Durgen Dirgehammer

Reliquary of Kings
Clear the Dark Iron Looters around Durgen's platform before pulling; Fear can send a player into those packs. After defeating Durgen, loot the head for Old Ironforge Incursion and search the vaults for the remaining heirlooms and the treaty tablet before leaving.
Durgen Dirgehammer
Durgen combines Rend with Fear, testing whether the group has cleared the vault room and can keep the bleeding tank alive when healing is interrupted.
Abilities

Fear
Strikes fear in an enemy, causing it to flee in terror for up to 8 seconds. Only 1 target can be feared at a time.
Clear the wall-side Looters before pulling so a fleeing player cannot bring them into the encounter.

Rend
Inflicts Physical damage to an enemy every 3 sec. for 15 seconds.
Keep healing through Rend between Durgen's weapon hits.
Tank- Keep Durgen in the cleared vault room. If Fear catches you, use an available fear break before reaching wall-side packs, then re-establish the fight in the cleared space.
Healer- Keep a health buffer on the Rend target so a Fear on you does not leave unanswered bleed ticks. Continue healing the bleed between Durgen's melee hits.
Damage- Keep damage on Durgen from the cleared part of the room. Use an available fear break if Fear would carry you toward surviving wall-side Looters.
