Highmaul

Kargath Bladefist

• Kargath Bladefist
• Drunken Bileslinger
• Iron Bomber
• Iron Grunt

Kargath's Berserker Rush cannot be stopped until he either kills his target, or finds something else to take his anger out on. As the fight progresses, Iron Bombers and Drunken Bileslingers rain destruction from the arena stands. Players can dispatch these creatures after being tossed into the crowd by Kargath's Chain Hurl.

• Damage Dealers: Iron Bombers and Drunken Bileslingers will continue to harass the raid from the stands until they are killed.
• Healers: Kargath inflicts massive damage to the tank with his [Impale] ability.
• Healers: Iron Bombers inflict raidwide damage until they are killed.
• Tanks: Kargath's [Impale] leaves [Open Wounds] on his target that increases the damage of consecutive Impales.

The Butcher

• The Butcher
• Night-Twisted Cadaver

The Butcher attacks relentlessly, hacking at his foes with his dual implements of destruction. His main abilities seek to target large clumps of enemies, and positioning is key to handling and overcoming his attacks.

• Damage Dealers: Players in melee range must form clumps of varying sizes throughout the fight to manage the Butcher's [Cleave] and allow [Gushing Wounds] to fade.
• Damage Dealers: Players at range must clump in order to survive the Butcher's Bounding Cleave sequence.
• Healers: Groups that are struck by [Cleave] suffer periodic damage from [Gushing Wounds], which can stack.
• Healers: All players in the raid suffer Physical damage when the Butcher begins his Bounding Cleave sequence.
• Tanks: [Heavy Handed] causes the Butcher to attack the player closest to his current target with a copy of all of his melee attacks. These attacks can be mitigated and avoided as usual. If another player is not close enough, the second attack will trigger on the primary target.
• Tanks: [The Tenderizer] will always hit. It cannot be dodged or parried, but it can be blocked.
• Tanks: [The Cleaver] will only apply its damage over time effect if the attack successfully lands on its target.

Tectus

• Tectus
• Tectus, The Living Mountain
• Shard of Tectus
• Mote of Tectus
• Night-Twisted Earthwarper

Tectus cannot be killed by traditional means. He builds energy, channeling Tectonic Upheaval whenever he reaches 100. Depleting Tectus's health before the end of Upheaval shatters it into two Shards of Tectus; otherwise, Tectus heals and resumes gaining energy. Each Shard splits into four Motes of Tectus when shattered. Players must kill all eight Motes to defeat Tectus.

• Damage Dealers: Deplete Tectus' health before the end of [Tectonic Upheaval].
• Damage Dealers: Move out of the rumbling earth before the eruption of [Earthen Pillar]!
• Healers: Players will take heavy damage during [Tectonic Upheaval].
• Healers: Move out of the rumbling earth before the eruption of [Earthen Pillar]!
• Tanks: Face Night-Twisted Earthshapers away from other players to minimize damage from [Earthen Flechettes].
• Tanks: Intercept [Gift of Earth] if you are not tanking Tectus.
• Tanks: Move out of the rumbling earth before the eruption of [Earthen Pillar]!

Brackenspore

• Brackenspore
• Fungal Flesh-Eater

Brackenspore emerges from the infested waters beneath the cliffs of Highmaul, spreading fungal growth that will engulf the beach if left unchecked. Players must use available Flamethrowers to keep Creeping Moss in check, while defeating hostile fungi that Brackenspore creates in his wake.

• Tanks: Grab the attention of Fungal Flesh-Eaters as they stream in from the sea.
• Tanks: Interrupt [Decay] which is cast by the Fungal Flesh-Eaters.
• Damage Dealers: Interrupt [Decay] which is cast by the Fungal Flesh-Eaters.
• Damage Dealers: Intercept the damage from [Spore Shot] away from other players, to avoid splashing the damage.
• Healers: Heal friendly mushrooms to full to gain their effects. Once they are healed to full they will begin to wither and die at an increasing rate. Keep them healed in order to maintain their beneficial effects.
• Healers: Heal Living Mushrooms to full to gain [Living Spores] in order to survive the damage caused by [Infesting Spores].

Twin Ogron

• Pol
• Phemos

The Twin Ogron combat players while performing attacks at specific energy thresholds. At 33 energy, an Ogron uses his special weapon attack. At 66 energy, an Ogron performs a large shout. Finally, at 100 energy, an Ogron performs a large, raid-wide attack. As the distance between the Ogron increases, their haste increases and casting time additionally decreases, reducing the amount of time players have to react to various abilities.

• Damage Dealers: Stand near Phemos for [Enfeebling Roar], as he splits damage, effectiveness, and duration amongst nearby targets.
• Damage Dealers: Be wary of the radius of [Whirlwind] and the path of [Shield Charge].
• Healers: Be ready to heal on the move when [Quake] and [Blaze] begins.
• Healers: Watch for [Interrupting Shout], as it will interrupt and lock you out of spellcasting for a short duration.
• Tanks: [Whirlwind] has a large radius, and can be deadly when combined with [Shield Bash].
• Tanks: Controlling the distance between the Twin Ogron is essential to managing the potency of their abilities.

Ko'ragh

• Ko'ragh
• Volatile Anomalies

Ko'ragh is protected by a Nullification Barrier that absorbs all magic damage taken. When the barrier is removed, he activates a rune that recharges it. While recharging, one player may also absorb some of the rune's energy and receive a Nullification Barrier. As the fight progresses, an increasing amount of Overflowing Energy orbs spill from the rune and float to the ground, exploding when they land. Players who have a Nullification Barrier can catch and absorb Overflowing Energy to mitigate the amount of raid wide damage and prevent a lethal amount of damage from occurring.

• Damage Dealers: Absorb [Caustic Energy] to gain a [Nullification Barrier].
• Damage Dealers: Avoid [Overflowing Energy] until you have a [Nullification Barrier]. Absorb [Overflowing Energy] when you do have a [Nullification Barrier].
• Healers: Focus intense healing on players absorbing [Caustic Energy] to allow them to survive the transformation.
• Healers: [Expel Magic: Fire] inflicts heavy raid wide damage and requires dispels to mitigate some of the damage.
• Healers: [Expel Magic: Shadow] absorbs all healing on the raid until it is removed.
• Tanks: Tanks marked with [Expel Magic: Arcane] must run away from their allies and avoid the periodic explosions.
• Tanks: Volatile Anomalies will spawn periodically during the charging phase. If they are killed within a [Suppression Field], they will not cast [Destabilize].

Imperator Mar'gok

• Imperator Mar'gok
• Arcane Aberration
• Displacing Arcane Aberration
• Gorian Warmage
• Volatile Anomaly

Imperator Mar'gok assaults players with destructive Arcane magic and summons Arcane Aberrations to fight for him. When Imperator Mar'gok reaches 85%, 55% and 25% health remaining, he activates one of the runestones in his throne room, augmenting his abilities with additional effects. The runestones activated at 55% and 25% must be awakened from their dormant state. As they charge, guards arrive to defend the Imperator as Volatile Anomalies pour from the stone.
