Call Spirit

This spell reaches out into the Ethereal plane and calls forth the closest available soul or essence of a sentient creature, and binds it to the dead body that is being targeted by this spell. The body being used for the spell must not have been dead more than 24 hours, cannot have died from old age, must have belonged to a sentient creature, and must be in sufficiently good condition as to be able to live again. (It cannot be missing any major organs, or all its blood, or a head, etc.)

The spell then returns the body to life using the soul or essence that was summoned. The DM can either choose what sort of sentient creature this soul or essence belonged to, or you can roll on the tables below to determine the creature type the soul or essence belonged to and its alignment:

The newly living creature will keep the Strength, Dexterity, and Constitution scores the body had, and gain the Intelligence, Wisdom, and Charisma scores that the soul or essence has. If these ability scores are not known Roll 3d6 for each ability score, re-rolling any score below an 8. The Traits that the creature has are the traits of whatever species the body is. If the soul or essence was able to cast spells or had any class levels it regains access to those abilities. To determine if the soul or essence had any levels in a class roll 1d10: 1-9 no class levels. 10: 1d4 levels in one class. To determine the gender identity of the soul or essence roll 1d3: 1. Male, 2.None / Neuter, 3. Female 

The process of being returned to life in a strange body is extremely taxing and the creature will return to life with 5 levels of Exhaustion, reducing this level by one for every day they spend resting or doing only light activities.
