There are no adds that are spawned in this event, however 2-4 mobs besides the Ixt and the Champ do not leave after the runt is killed. These extra mobs will add at a later point in the fight if not killed before hand.
Question Do the roamers in the halls and mobs from the south room always assist her when she is engaged? The last time we did this there where no more then 2 mobs in the west hall roaming. We tanked her in the SW corner and when we had her at 75% we ended up with at least 10 adds. Golems being the majority of them (and the Golems are not roamers).
Yeah this is an old post, but all that happened in the above situations is that they aggro'd one of the roamers probably by getting blasted too far into the corner, the roamer couldn't figure out a good path for whatever reason and ended up pathing thru a bunch of random parts of the zone to get to the raid gathering adds as it went.
anyone have any info on this mob... AOE she cast.. what does she hit for... does she quad.. best type of spells to use on her.. IE fire base.. ice base... etc
