Would have had it but I made a critical mistake. I went back to town to repair. That will randomly put you in another group when you come back. It put into an instance where the boss was dead.
I should have just stayed with the first group even if my gear was broken. It was almost down.
It is not impossible at all, but people should be on T1 and have poison resists, etc.
Next time…so now I wait for next spawn.
