When it comes to the Succubus I used the following skills to defeat her.
1. Level two Skelaton Wall
2. Level four Metorstrike
3. Level four Aura of Gaurding
I would hammer the Succubus with Metorstrike while she was distracted by the skelatons. Just in case she got too close to me, a level 4 Aura of Gaurding proved to be good protection.
This is how I defeated the Succubus, but you are welcome to dance to whatever drumbeat you want to dance to.
