You create an inky portal to an otherworldly dimension under a creature in range. The creature must make a dexterity saving throw. On a failed saving throw the creature takes 3d8 piercing damage and is trapped in the maw. In the maw the creature is in full cover, blinded, restrained and takes [[3d6]] acid damage at the start of each of its turns. On a successful saving throw the creature takes half the initial piercing damage an is not trapped. The creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
