Untrue Resurrection

Touch a creature that has been dead for no longer than 200 years and did not die of old age. If the soul is free and willing, it returns to life with all hit points, but its creature type becomes undead and it is bound to you by grave-oath. While bound, it is charmed by you and can communicate telepathically with you while on the same plane. It may repeat a WIS save once every 30 days, ending the charm on a success, though it remains undead unless restored by a Tier 10 restoration or story effect.
