Description
You put forth your Ethereal energy and touch another creature's Pneuma. Using your control over the energy you disperse each other's life essence and equalize it. The creature must succeed on a Constitution save or become part of the equilibrium. Take your and the creature's current hit points, add them together and divide by 2, the number (rounded up) is now your and the creatures new current hit points. If this number succeeds your hit point maximum, you gain the rest as temporary hit points, the same counts for the other creature.
