[zone=3456] The Arachnid Quarter The Plague Quarter The Military Quarter The Four Horsemen The Construct Quarter Grobbulus Frostwyrm Lair Grobbulus is the second boss of the Construct Quarter of [zone=3456]. says about him: Grobbulus, the first of what was to be an army of flesh giants. It carried the plague slime of Naxxramas within its body, injecting the living ooze into the bodies of its foe. The recipient of this foul injection would usually flee to his allies, bringing them down with him.

Overview Grobbulus is an encounter that requires the attention of Tanks, DPS, and Healers alike. The Main Tank will need to watch the ground for Poison Clouds and kite Grobbulus in a circle around the room, with the melee DPS following behind the boss. The MT should also make sure to move Grobbulus a sufficient distance, so the melee doesn't get caught in the last Poison Cloud. An Off Tank will need to watch for any Fallout Slimes spawned by players hit by Slime Spray. Ideally, only the MT will be hit by this (thus, only one Slime), but sometimes the melee DPS will spawn a few as well. In addition to this, everybody except for the MT will need to watch for the Mutating Injection. Everybody with this debuff will need to run to a point behind Grobbulus (usually 2-3 Clouds back) and wait for the Injection to wear off there. Classes with spells that remove diseases need to not get rid of this disease, because a Cloud dropped early may harm the raid. Abilities (Spell #28240) - Every 15 seconds Grobbulus will spawn an expanding Poison Cloud underneath himself. Clouds will deal 2000 Nature damage to people standing inside them, and will last for 75 seconds. (Spell #28169) - Grobbulus will cast these every ~20 seconds in the beginning of the fight, and more frequently as time passes. People injected with it will drop a Poison Cloud when the disease is removed (either after its 10 seconds expire, or after it's removed by a spell), and will deal 8,075 to 8,925 Nature damage to nearby allies. (Spell #28157) - A frontal cone spray that deals 6,300 to 7,700 (25 Player: 11,875 to 13,125) Nature damage. Every player (pets are not affected) hit by the Spray will spawn a Fallout Slime. - Spawned from players hit by Slime Spray, those deal 1,000 (25 Player: 2,000) Nature damage every 2 seconds to everyone within 10 yards of them. (Spell #26662) - 12 minutes after engaging Grobbulus he will Enrage, increasing attack speed by 150% and damage done by 500%, wiping the raid almost instantly.
