Visions of Grandeur

Trying to take down Grieg Veneficus in Grieg's End but can't target or engage. I can see him and his 'trigger' on my mq2 map though. Anyone taken him down or know what to do?

Thanks in advance.

I have killed him on many occasions without problem, I just go through the locked door in Skele form, just kill all the adds on the way up, then engage him.

You could try getting the key and do it properly once.

Cheers
