Void Wall

Call on the power of the void to summon a wall of transparent energy that blocks incoming or outgoing ranged attacks with a 15 ft width and 10 ft height. All entities can pass through the wall freely. Standing on where the wall’s area is does not protect from attacks. It can block melee attacks if it is between you and your attacker. At first level the spell has 20 hp. The hit points increase by 10 and the duration increases by 2 rounds for every spell level above 1.
