* Upon casting the shield, the creature becomes engulfed in a protective shield, which will block all incoming damage. It will break after sustaining a certain amount of limb damage. If an energy shield is already active, the technique can be used again to refill the existing shield's HP back to full.
** The shield counts as an Armored target with 30 HP and LDV-0.
** The shield is fully impenetrable until broken - there is no pass-through of damage until the shield is broken, which makes it possible to survive powerful hits without taking damage (other than the casting costs), even if they would destroy the shield in one hit.
