Jardin the Conqueror says, "What are you doing here, Cryomancer? I do not need your help against these weaklings!"
Have not quite figured that part out yet, but I think he banishes them if he sees them.
Theres a few more things here. The goo's have to be attacked range, if you attack them melee, it kills you. Also, it didnt seem they took any damage at all anyway, so your better off just going strait burn hard on Jardin. Also, one of the curses will change the persons screen color, that curse cannot be cured or its a fail mechanic.
Goos spawn around the area that multiply and buff named if not kept at low or no HP. Position named in a location convenient to send pets or some ranged dps on the initial blobs that spawn. Hard burn named before blob buffs overwhelm raid. Additional adds spawn causing a stun, immunity items work.
Anybody willing to share information on this encounter?
