Thanks, I think you helped smile

I built the Ghoulish Head-based creature and maybe it did the trick. Also putting some points into Healing might have helped. Otherwise yes, I'm using Way of the Ranger and the other skills that increase damage and Hide in Shadows to get some time to heal. I did put 9 points into Way of the Ranger this time and got the splitting arrows skill to 10. One of those up close can do huge damage.

Anyway I don't think you can disable the summoning chambers. I think this is supposed to be done really quick.

In the end the creature killed him while I was busy disabling the chambers, hehe. I did reload three or four times though.

Cheers
