This mod adds a new spell to conjure a floating skull. It is an apprentice level spell, and is stronger health wise than an ice wraith, but does less damage. It also absorbs health with it's attacks. And it also has a cool new casting effect that spawns the skull in a ray of red mist. It's pretty dope. (albeit a little tedious)

You can find the spell tomes for this in 3 locations. They are these listed below:

Anise's Cabin cellar - In the bookshelf
Mara's Eye Pond - In a crate
Kilkreath Temple - In the final room, on the table to the left.

If you have any suggestions go ahead and say them. I might add some.
