YOu only have to kill the succubus, the rest dies when she dies. Just walk/run on till you meet her and beat her up whatever way you want. (she relativly easy)

when i fought the succubus i think i used a level 3 or 4 freeze and that worked very well...i managed to kill her by using only one freeze <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
