Corrupted Wildshape [Monstrous]
You have learned to use the necromantic energies that power your undead form to overcome the inability of undead creatures to wildshape. You can assume the form of an undead, rotten creature with the use of your wildshape ability.
Prerequisites: Undead type, wildshape class ability.
Benefits: You can use your wildshape ability even though you are undead. The ability functions just as if you were a living creature using the ability, with the following exceptions:
You do not gain a Constitution score in the new form, and you retain all of the immunities of the undead type while in your new form. The form you assume looks half decayed, with missing patches of fur and rotted worm-eaten flesh. While in this form, the rank odor of death hangs around you.
Normal: Since it is based on the polymorph spell, wildshape works only on living creatures.
