Charged Tendril

Conjure a coiling whip of lightning into an empty hand. For the duration, target a creature within 10 ft. and make a melee spell attack. On a hit, deal Lightning damage equal to 1d12 + Your Spellcasting Modifier.

On each subsequent turn, you can use your action to make another melee spell attack against a target you can see in range.

At higher levels: By casting this spell using a spell slot of 2nd level or higher, increase lightning damage dealt by 1d12 per spell level used.
