Ethereal Shot

As a bonus action, you summon an ethereal hand cannon to your grip. On each of your turns until the spell ends, you may use your action to attack a target you can see within range using your spell-casting modifier. On a hit, the target takes 2d6 (fire/cold/acid/lightning) damage (of your choice).

When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every two slots about 1st (3rd- 3d6, 5th- 4d6...).
