Each Elder in the Council has their own set of abilities, and the fight requires three tanks to pull off successfully. But it's not that easy, of course. Also present in the fight is the pesky spirit of Gara'jal, last seen in Mogu'shan Vaults. Gara'jal will possess each Elder in turn, changing the Elder's abilities and making the fight just that much more hectic for players.
This fight has a very heavy emphasis on target swapping between both the various Elders, and the adds that those Elders spawn. Players must attack the Elder that is possessed by Gara'jal -- otherwise a raid-wide AoE will quickly stack to unmanageable heights and overwhelm the raid. In order to force Gara'jal to swap to another Elder, players must DPS the possessed Elder down by 25%.
