I had my thief....(lvl. 14)swashbuckler put up four traps right next to the entrance.
Then I protected my tanks from dead and walked them into the room...spread ´em out.
Then I let my thief stroll into the cirkel room.
Lich talks...then teleports right into my traps and...dead he is!
The rest of the people are just hack´n slash...but take out the female mage....she´s pretty tuff...I had my tanks rush her...and my paladin with Carsomyr was just to much for her
