Boxing war/sham with a friend boxing necro/bard we tried to burn it down and by the time the mob was at 20-30% we had about 15 adds may more. we didnt survive it. friend had to go. so i stayed to test out the spawns. This much I do know. It spawns adds at 90% and 80% hp. Not time based as i was just wacking it with my sword, no dots or pet from the shammy. The adds have a decent amount of hp and do not die fast like other add spawns ive seen in this expansion. They hit for ave of 1200 on 6.3k war not useing defense.
Just so happens my mage friend popped on and came out........we killed it just like in previous posts BUT.....when mob was at 8% mage pet got KOed and it summoned shammy......adds DID NOT agro...shammy died instantly. name ran after mage so warrior jumped in and finished it.
85 necro War pet 85 Mag Earth pet 2 Cleric T5 Mercs Adds wont Aggro off pets so if you fight it at Range it a Easy easy Fight Just dont get summoned or all Adds will come down on you Let pet tank name.. Adds hit for about 2.5k max if you have a Real PC Tank it all adds aggro makes it a hell of a fight
