Argaloth

Argaloth is the first boss in Baradin Hold. Similar to Vault of Archavon the winning faction of Tol Barad allows access to this boss.

Unable to contain the massive Pit Lord Argaloth in the cells of Dalaran's mighty Violet Hold, the magi of the Kirin Tor were left no choice but to confine the powerful demon beneath Tol Barad.

Strategy
For this fight you will need to split your raid into two groups (one tank in each group). One group will stand on his left and the other will stand on his right, all players in each group will need to stack on the tank so as to mitigate his Meteor Slash.

The Meteor Slash applies a debuff to the first tank. The second tank immediately taunts to prevent further damage to the first tank. The first tank should retaunt Argaloth just as his debuff disappears, which will be two or three seconds after Argaloth Meteor Slashes the second tank; this means that for those two to three seconds the second tank will be taking increased damage. Repeat this pattern until 66% at which point Argaloth will cast Fel Firestorm. The raid immediately spreads out and keeps moving while attacking if possible, as Argaloth will cast a shower of fire that will drop fires under players causing roughly 8k damage per tick.

Once Fel Firestorm is over quickly restack on the tanks in the begining positions. The Meteor Slash debuff will be cleared from both tanks, who repeat the taunt rotation. Argaloth will again cast Fel Firestorm at 33%; again quickly spread out and watch out for fire. Again restack on tanks and continue with taunt rotations.

Consuming Darkness can and should be dispelled immediately.
