Seeing that RD is working on the wildshape modifications, it might be a good time to point out that the zombie form with polymorph self does not have the ablities listed that a zombie form should have. Immunity to sneak, Immunity to level drain, healing hurts negative heals, etc.
Zombie form (Polymorph Self)
No it has 10/- for all damage types I think.
"Polymorph Self" and "Shapechange" forms are going to be completely redone, similar to the upcoming Wildshape forms. We'll keep this in mind.
This remains a known issue. It's not really a bug, though, so I'm locking this thread.
