Fourth Wall. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 44 (6d12 + 5) slashing damage. If the target is a creature, it is grappled (escape DC 20). The target is encased in four walls of paper, each with AC 12 and 30 hit points, and with a vulnerability to fire. Until this grapple ends or all four walls are destroyed, the target is restrained, and The Primordial can't use Fourth Wall on another target.
