2 - This is a locate that works on anyone who is dead, regardless of where they are.
3 - You can speak to the souls of of dead individuals, maybe cast vigil on them. They can't talk back.

Requires Soul Bonding, maybe revelation.

> I love this idea. I'd find it particularly cool if whatever the offensive action is, it's based on Theurgy/TM. If it trained those two, then WOOF, that'd be awesome. I'd like for it to lock out something though, either weapons ("your hand passes through the broadsword!") or TM, and maybe damage dealt to you while in this form does spirit damage instead of vit damage.

Interesting idea. I think it's a fair trade-off to take spirit damage if you're dealing spirit damage. Maybe a passive drain that's off-set by absorbing spirit health from others. Theurgy reduces the spirit damage, and trains it when you take a spirit draining action.
