Incorporeal vs corporeal undead

Which are which?

I see ectoplasm can only be harvested from wraiths and spectres.  Does that mean those two are the only incorporeal undead?

Yep - that's all.


Until some ambitious necromancer makes new ones.

Yes, that's all. We added a nice bundle of corporeal undead in L&E, but no new incorporeal ones.

Thanks for the clarifications, everyone!
