Abilities:- Enrage at 12 mins mark.
- Poison Cloud Leaves a poison cloud 10 yards wide behind him. The cloud deals high amounts of Nature damage, meaning the MT needs to keep moving while tanking. The poison cloud remains for a very long time.
- Slime Spray Hits for 3600-4800 Nature damage. Party members who are hit will spawn a Fallout Slime.
- Mutating Injection Injects a target with a mutagen that will do a 4500 physical damage AOE after 10 sec, or a lower-damage AOE when cleansed. The target will create a poison cloud with the same effect as Grobbulus himself, so the target will need to run to the side when cleansed to avoid damaging the rest of the raid.
Strategy:He needs to be tanked in a circular motion around the edge of the room. All raid members must stay out of the poison cloud.
He does Mutating Injection on random people, and they explode if not cured. They explode if they are cured as well, but for less damage. Once the effect ends, the target begins leaving behind a poison cloud similar to Grobbulus'. Therefore, do not cure injection targets while the person is near the raid group, or else you will wipe the raid.
Melee should focus on the spawned slimes, the ranged DPS should focus on Grobbulus himself.
Rinse, repeat until dead.
