The caster eats at least a portion of the flesh of another creature’s corpse. Thereby gaining one-quarter of the creature’s Strength score as a bonus, and 4d8 temporary hit points. At the end of the hour, the caster must perform a Constitution saving throw versus the caster’s DC— upon a failure, the caster takes an equal amount of necrotic damage to the temporary hit points, which may not be reduced in any way; also gaining one-level of exhaustion. Upon a success, the caster takes necrotic damage equal to half of the temporary hit points.
