Gary13579 say true.
Only 'do' in Water Form , (can't Water bomb the main tank ) but , the enrage timer can kill u .
I think u need 10 raiders , 9 dps man ranged and 1 healer, a extra dealing dps for the kitter . ( Warlock affli perhaps )
Need a good kitte and good place for don't taking the aura and water bomb .
3 500 000 health , 10 min timer enrage , need raid dps = 5900 dps .
Maybe with 8 guys or if u have a really good dps 5 men but solo ....
+rep for the information and a futur + rep for the kitter ^^
