Is it modified to be able to cast upon a corpse yet? (PC or ones you find/buy)

I don't think so, though you're free to contact a DM if you're interested in raising a PC that way.

I was asking because it is a very horrible spell, and I heard that it was being implimented so that you can raise object corpses you buy/find.

It's been in the works for some time now. I'm sure we'll let the playerbase know when it's close to completion.

I assume we can ask a DM IG if we want to animate a corpse (PC or Object)?
