Warbringer O'mrogg is a two-headed Ogre. He is the second boss in The Shattered Halls wing of the Hellfire Citadel instance. Attempting to skip O'mrogg and move on to Kargath Bladefist causes O'mrogg to add to the Kargath event.

Adventure Guide

The ruthless and cunning ogre O'mrogg is considered one of the Fel Horde's deadliest members. But this feared brute has a problem. The ogre's two heads have always struggled to agree on even the simplest matters. Two years ago, O'mrogg began a twelve-step plan to develop a synergy between his warring personalities. His heads have yet to decide on which step to start with.


  • Spell nature thunderclap.png  Thunderclap Magic Effect — Warbringer O'mrogg inflicts 938 to 1062 Nature damage to nearby players, reducing their attack speed by 35% and slowing their movement by 35% for 10 sec.
  • Ability warrior focusedrage.png  Beatdown — Warbringer O'mrogg chooses a random player and beats them down, clearing all threat and giving a large amount of threat to his Beatdown target.
  • Spell shadow possession.png  Fear Magic Effect — Warbringer O'mrogg strikes fear into all nearby players, causing them to flee in terror for 3 sec.
  • Spell fire flametounge.png  Burning Maul — Warbringer O'mrogg ignites his maul, inflicting 2880 to 3520 additional Fire damage with each melee attack for 18 sec.
  • Spell holy excorcism 02.png  Blast Wave — Warbringer O'mrogg unleashes a wave of flame, inflicting 2544 to 2956 Fire damage to nearby players and reducing their movement speed for 6 sec.


  • O'mrogg has two heads. When he emotes, he switches aggro tables. As such, DoTs should be avoided for this fight, as well as HoTs.
  • Although he cannot be taunted, high aggro moves will pull him off his target. Warriors can stack Sunder Armor, druid bears can use Lacerate. Druid moonkin can easily pull him off a healer with a large Starfire crit and given their high armor can take the abuse from him long enough to either wait for him change targets or let the tank re-establish aggro.
  • His melee damage is not significant, 700-900 against plate wearers or bear druids.
  • He will periodically AoE fear. Tremor Totems, Fear Ward, or Will of the Forsaken, are all helpful. "Stance dancing" is rather difficult, as it does not appear that his fear is timed or announced. He will temporarily shift focus to anyone not feared, so if you do not have a method of making the tank immune to fear, it may be wise to make sure everyone is in range to be feared.
  • He will periodically thunderclap. This will cause 900-1000 nature damage to all targets within range. At level 70 this amount of damage is really not significant, but the slowing effect needs to be removed from melee if possible so that they can continue to DPS, and be able to get out of range of his blast wave.
  • His highest burst damage output is from his Burning Weapon and Blast Wave combination. When his weapon glows red, it will hit the target as fire damage for up to 1000. Immediately following, he will strike the target and AoE Blast Wave for up to 3200 fire damage. Usually after he does a Blast Wave he will do another after only a few seconds. Fire protection potions, fire resist totem, Gift of the Wild, or fire resist gear are all helpful.
  • Tank him in the middle of the arena that he starts in. Be careful of the guards in the hallway nearby, and the possible assassin near the far edge of the arena. You can typically clear this assassin from the outer edge, prior to engaging O'mrogg.
  • For Paladin tanks, it's a good idea to use Seal of Vengeance and let it tick. If you stack it up to 5, it will tick on the boss when the aggro table changes and will help you get aggro back.

Heroic Mode Strategy

  • An effective heroic strategy is to put three members of the party in DPS gear while maintaining about 8500 hp (buffed). This includes the tank. The two remaining members should be healers, also with high hp. Tank goes in first and then the other two DPS shortly follow. Healers heal whomever has aggro. He will inevitably hit a healer, but with DPS going all out, it shouldn't be for very long. The other healer should be able to heal through it. Healers try to stay inside the fear range so as to not pick up aggro during the fear. Zerg him down.
  • On O'mroggs first threat list change all dd should cease fire for a few seconds while the tank goes all out. Done correctly, the tank will be first on both aggro lists. However, the tank needs to keep up high dps throughout the rest of the fight so he wont lose aggro on either list.


Omrogg appears to possess two threat tables (or an aggro wipe that makes it appear as so.) When he emotes, he switches tables, which, when it occurs for the first time, is an effective aggro wipe, except for one person (not the tank) who is assigned a small amount of threat. Use no DoT effects or HoT, and keep the tank topped off to lower the likelihood of non-tank aggro right after a table switch. The tank should immediately attempt to gain aggro after the switch, as all DPS ceases until he has control.
