Shield
A shield weapon encapsulates the target in a short-term force field. This force field lasts until the start of your next turn or until it has absorbed the listed amount of damage, whichever occurs first. A force field originating from a shield weapon blocks only incoming damage; it does not interfere in any way with the target’s weapons or attacks. You can’t use a shield projector to target yourself.
