A canopic shade is actually three separate creatures: a corporeal undead known as a canopic corpse, and two incorporeal undead canopic shades, one known as "the heart" and the other known as "the brain".
Creating a Canopic Corpse
“Canopic corpse” is an inherited template that can be added to any corporeal undead (referred to hereafter as the base creature).
A canopic corpse has all the base creature’s statistics and special abilities except as noted here.
Turn Resistance (Ex): A canopic corpse has +3 turn resistance. If the base creature already possesses turn resistance, it gains a +3 enhancement bonus to its existing turn resistance.

Malevolence (Su): Once per round, a canopic shade can merge its body with a creature on the Material Plane. This ability is similar to a magic jar spell (caster level Xth), except that it uses the canopic jar as a receptacle. To use this ability, the canopic shade must try to move into the target’s space; moving into the target’s space to use the malevolence ability does not provoke attacks of opportunity. The target can resist the attack with a successful DC X Will save (for the brain) or DC X Fortitude save (for the heart). A creature that successfully saves is immune to that same canopic shade's malevolence for 24 hours, and the canopic shade cannot enter the target’s space. If the save fails, the canopic shade vanishes into the target’s body.
"Essence Drain (Su): Once a canopic shade has successfully used its malevolence ability and merged with a victim, it begins to drain the victim's essence. Each round, the victim must succeed on a DC X Will save (for the brain) or DC X Fortitude save (for the heart). Failure indicates that the victim suffers 1 point of ability drain (Charisma for the heart, Consititution for the body). A victim reduced to Cha or Con 0 in this manner dies, and the canopic shade is immediately destroyed as well.
Each round that a victim succeeds on its saving throw, the canopic shade suffers 1 point of damage. If a canopic shade is destroyed while merged with a victim, a tiny spark of stolen essence bursts forth, granting the victim 1d4 temporary points of Charisma (for the brain) or Constitution (for the heart). These temporary ability scores last for 24 hours.
