Hmm, I stole all of the oil barrels before I triggered Alexander and his crew. After that I positoined them on the eastside of the building, send out one character and sacrificed him in the hope that he would take one of the Bishops servants with him. After that I entered with the rest through the mainentrance. Luckily the Voidworm already appeared, so Alexandar and his gang were kept busy, while I decoyed the meele-fighters away from him. With the fighters gone I waited. The worm is a strong bastard, but with his poisonclouds he widened the fire, so in the end it could have been worse
. After the worm was killed, I killed the rest without big problems.
I was also only Level 7, so yeah, it is manageable! You can do this!
