Accept Soul (3.5e Spell)

With enough of these, you are certain to go completely insane.

As reincarnate, but the target is reincarnated as a Stationary Sentient Illusion inhabiting your mind. If they don't wish to be reincarnated as a Sentient Illusion, they are still reincarnated as a Sentient Illusion if they fail their Will save. Unlike reincarnate, accept soul works on constructs, elementals, outsiders, and undead.

Material Component: Peculiar-smelling incense and powdered metals, burned over the remains, worth a total of 1,000 gp.
