Argaloth Pit Lord strategy, Baradin Hold
This badass has a 5 minute enrage timer, so you will need to have a good team capable of burning him down. He does 3 basic things to your group. Meteor Slash, Consuming Darkness, and Fel Firestorm.
To start off the fight, you want to split your raid into 2 relatively equal groups before you do your pull. Once you’ve begun to run in, you will want to stack DIRECTLY on top of your tank (2 tanks regardless of its 10/25 of course). One group to his left, the other to his right. One of the first things you’ll see is his Meteor Slash. If you’ve played WoW before Cata this probably won’t be a new mechanic for you. In 25 man, this will drop 475k damage split between everyone on the side of the tank that currently has aggro (200k for 10 man). Once the Meteor Strike’s gone out, it will leave a debuff called Meteor Slash, which makes it necessary for your opposite tank to then taunt so that no one side is taking consistent strikes. The debuff stacks, which increases the fire damage taken.
The second thing you will notice, and in short order of the fight starting, will be the Consuming Darkness Magic debuff. This needs to be dispelled as FAST AS POSSIBLE. For our 25 man group, we assigned healers to cover the groups. Priests are pro for their mass dispel, but Shamans and Paladins work too. Its important to dispel as soon as possible as the debuff causes 3900-4100 damage every .5 seconds and lasts 15 seconds or until dispelled. Nasty business that.
At 66% and 33% he will stop his meteor strikes and debuffs and cast Fel Firestorm. Its important for your group to break up a split second before this casts and scatter away from anyone nearby. Small green meteors will fall from the sky, and forms Fel Flame on the ground where they land. Avoid these as much as possible as the fire causes 8.2k to 8.8k of damage for as long as you are standing in them. Have your locks pass out health stones before the fight, or make sure you have health pots for this as your healers will also be separated and running as well. Run back to your tanks as this ability begins to end.
Aside from this, much of your fight will depend on whether your dps team can get him down before the 5 minute berserk timer goes off and your raid gets slaughtered. If you can manage it, enjoy your first taste of T11 and pvp gear!
