Essence Siphon

You choose a creature within range and they must make an Intelligence saving throw. On a failed save the creature take 10d6 force damage as the pure essence of their mind is picked from their body. On a successful save the creature take no damage. The essence is rolled into an orb of pure energy. This orb floats around your person for 1 hour or until dispelled. This energy can be used to either cast Weave spells. Or you may use a bonus action to heal an ally. You determine the amount of energy is used on the ally. If the essence needed from the spell requires more than what's left from the orb the damage will transfer over to the caster.
