After taking a look at MythAdvocate's mutation package system I decided to try out myself on his thread. But since I didn't get any replies I moved it into my own thread. Hopefully I'll get more help here.
Spirit Mutant
From mighty demon lords to lowly gods of hills, forests and cities to haunting apparitions and even the fae, this world contains a motley group of spirits and spirit touched creatures. These spectral or semi-divine beings are demonic, godly, netherworldly or fae in origin. Some are pure blooded members of their kind while others are the semi-mortal descendants of these spirits or earthly creatures mutated by their prolonged presence since their conception.

I'm trying to think of some more good spirit "mutations", but I'm drawing a blank right now. Can anyone help me with this?
