The Beguiling Corpse

One undead creature you touch is transformed and preserved. The target must have a majority of it's skin, bone, and other elements of a body for this spell to take effect. The undead gains 1d10+5 temporary hit points, and appears to all to be a living, breathing creature with a heartbeat. The creature cannot speak on it's own, but you can use your action to cause the creature so speak words of your choice. A creature that spends an hour to examine the creature can determine that it is an illusion with a successful Wisdom (Medicine) check against your spell save DC.
