Polymorphism tweaks and balance

[CatzCatzCatz]

One thing I'd suggest changing about Polymorphism is that it shouldn't change your voice and that the transformation should be visually distinct (I'm talking like your character makes a crunchy exploding sound followed by a pool of blood on the floor that you will have to clean up if want to do a good impersonation). Having it empowered removes the bleeding effect but it will still not allow you to change your voice to the stolen identity.

Also, an option to turn back into yourself would be nice if you had that gene.
