Cameo’s Arcane Whip

You create a lash of red, crackling arcane energy that strikes at one creature of your choice that you can see within 30 feet of you. The target takes 2d6 lightning damage. The target can make a strength saving throw to break free at the beginning of it’s turn. On a failure it remains restrained and you can use a bonus action to deal another 2d6 lighting damage.
