Tyrannosaurus Bite

You conjure an ethereal tyrannosaurus rex and direct it to bite one creature you can see within reange. Make a melee spell attack against the creature. On a hit, the creature takes 4d12 + your spellcasting ability modifier in piercing damage. If the target is Mediun or smaller, it is grappled (escape DC 17) until the end of your next turn by the ethereal beast. While it is grappled, it is restrained.
