Adventure Guide

As Azeroth's champions and their red dragon allies assault the gates of Grim Batol, the malefic General Umbriss leads the fortress's cultists and twilight dragonspawn defenders.


  • Ability backstab.png   Bleeding Wound Healer Alert —  General Umbriss savagely attacks his current target, inflicting his normal melee damage and an additional 860 to 1000 (2220 to 2580) Physical damage every 2 seconds for 10 sec. Healing the afflicted target to above 90% of their maximum health also removes the effect. Instant cast.
  • Ability warrior charge.png   Blitz Deadly —  General Umbriss sets his eye on the location of a random player, then charges to that location. When Umbriss reaches the location, he inflicts 6045 to 6355 (29250 to 30750) Physical damage and knocks up and away any player within 6 yards. 3 sec cast.
  • Spell nature earthquake.png   Ground Siege —  General Umbriss faces the location of a nearby random player, and then unleashes a massive ground tremor towards that location. The tremor inflicts 4533 to 4767 (17550 to 18450) Physical damage and stuns any player within a 20 yard long and 60 degree wide cone for 4 sec. 2.5 sec cast.
  • Spell shadow deathpact.png   Frenzy —  When General Umbriss reaches 30% of his remaining health he enters a frenzy, increasing his attack speed by 50% and damage by 50% until the encounter ends. Instant cast.
  • Trade engineering.png   Summon Skardyn —  General Umbriss periodically calls for the Troggs from the ruins behind him to join the fight. One Malignant Trogg and three Trogg Dwellers leap down and join the fight. Instant cast.
    • IconSmall StoneTrogg.gif Malignant Trogg — Malignant Troggs have low health and are cursed with Modgud's Malice.
      • Ability warrior trauma.png   Claw Puncture 5 yd range —  A Malignant Trogg sinks its claws into its current target, inflicting 72 to 77 (243 to 256) Physical damage every 3 seconds for 6 sec. This effect stacks up to 10 times.
      • Spell shadow grimward.png   Modgud's Malady Magic Effect —  Modgud's Malady inflicts 1755 to 1845 (5850 to 6150) Shadow damage every 2 seconds and reduces the movement speed of the affected player by 50% (25%) for 10 sec. In Heroic Difficulty Modgud's Malady stacks up to 10 times.
      • Spell shadow curse.png   Modgud's Malice —  When a Malignant Trogg dies, it casts Modgud's Malady on all players within 8 yards. In Heroic Difficulty a dying Malignant Trogg will also cast Modgud's Malice on General Umbriss and Trogg Dwellers within 8 yards. Modgud's Malice increase General Umbriss' damage by 100% for 20 sec. and transforms Trogg Dwellers into Malignant Troggs.
    • IconSmall StoneTrogg.gif Trogg Dweller — Trogg Dwellers have low health.
      • Ability warrior trauma.png   Claw Puncture 5 yd range —  A Trogg Dweller sinks its claws into its current target, inflicting 72 to 77 (292 to 308) Physical damage every 3 seconds for 6 sec. This effect stacks up to 10 times.


Periodically summons 1 Malignant Trogg plus 3 Trogg Dwellers, starting shortly after the pull. The malignant ones are purple and always spawn on left side when you are facing General Umbriss. There will only be one malignant trogg alive at any given time. If the malignant trogg is CC'd, the next summon will only have 3 trogg dwellers.

The Malignant Troggs apply a stacking debuff on their melee target. It also has the curse Modgud's Malady. If it is killed near another trogg or the boss, it will spread the disease to other Troggs or General Umbriss, and enrage them. Therefore it must be killed away from other troggs and the boss. Alternatively, it could be CCed throughout the entire fight. To complete the achievement  [Umbrage for Umbriss], the malginant trogg should be CCed, and then released at around 10-15% and brought to the boss (either by a high threat dps, death grip, or a tank taunt) and killed.

Tank and melee must be careful to avoid Ground Siege. It's a front aoe, and Umbriss does not move while casting, so it is very easy to dodge.

Healer needs to watch for Bleeding Wounds on tank, and heal the tank to at least 90% to prevent the debuff from doing any extra damage.

Ranged and healer need to watch for Blitz being cast on them, and move away if it is. This works like the charge stun from Icehowl in Crusader's Coliseum, charging the previous location of the targeted player. When the ability is announced, the targeted player should quickly move away (and out of the route of General Umbriss). Any player can be damaged or killed by this ability, so all players near the targeted player must also move. Cloth wearers can be one-shotted by this ability.

At about 30%, Umbriss enrages (Frenzy). A hunter may use [Tranquilizing Shot] to remove it. Otherwise everyone should use any cooldowns left and burn him down before the damage on the tank overwhelms the healer. Alternately, he may be kited.

As a final note to skinners, he can be skinned, but this requires 530 skill. Presuming you have maxed your skill at 525 and are not a worgen, you will need a glove enchant, and either  [Pip's Skinner] or  [Zulian Slasher]/ [Zulian Slicer].
