Dragonmaw

You lift into the air, transforming your head into that of a dragon's and moving 15 feet in any direction. You can then make a melee spell attack against a creature or object within 5 feet of you. On a hit, the target takes 6d8 piercing damage.
If the target is Medium or smaller, it is restrained in the dragon's maw until the end of its next turn.
At Higher Levels.
When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
