Bloodcrystal Raven Skull
This perfectly crafted raven skull is roughly a foot long and made of red-tinted crystal. A pale light flickers within its depths, seeming to react to your presence.
Wondrous Item: 225,000 gp
Property: (minor action) Store two healing surges in the skull. Up to seven different creatures can store healing surges this way. Each creature can store only two surges and takes a -2 penalty to death saving throws while any surges are stored. The skull consumes the surges during any extended rest.
Property: The healing surge stored within the skull is enough to allow the Raise Dead ritual to work even in the absence of any other part of that creature.
Property: If a creature that has one or two healing surges stored in the skull would suffer an effect or attack that traps or destroys the soul, the skull instead draws away the harmful effect and consumes the stored surges.
Power (Special, Healing): No action. If a creature that has two healing surges stored in the skull would die, that creature instead regains hit points equal to its healing surge value, using up one of the surges stored in the skull. That creature is at -1 to all attack rolls, skill checks, saving throws and ability checks until it reaches its next milestone. Each creature that has healing surges stored in the skull can use this power once per day.
