Barrier Wand

You can use a charge of this wand, and an action, to create a magical force field 5 feet around you. Any creature within 5 feet of you is pushed back and knocked prone. The force field has 30 hit points, and it breaks when it drops to 0. It has resistance against all damage except bludgeoning, and vulnerability to bludgeoning damage. You cannot be hit until the force field is destroyed.
