my first time ever tanking that boss i failed hard on the run and got 7 stacks of locus, ever since i have not moved in this fight, i just pop shieldwall, when i se him start his cast, makes this encounter a joke, the first add that comes i always grap and tank togther whit the boss, but the add in the locus phase i cant build aggro on, so we have an ot grap it, and always tank him at the dor were the adds spwan.
