Curse of Temporary Revival

This spell creates an undead servant. Choose a pile of flesh or bones that hasn't been dead for more than 3 hours. Draw some of its blood and a drip of your own, infusing it with the image of life you would want it to have. The pile of flesh/bones turns to ash as a familiar now stands  on it who can serve only you, and can communicate telepathically. The creature given birth to with this ability cannot be of a bigger size than you, and cannot be alive for more than 3 hours. You cannot have more than one creature of this type under your control at the same time.
