Thunder Bolt

You hurl a bolt of thunder at a creature within range and the thunder energy explodes on impact. Make a ranged spell attack against a creature and on a hit, the target takes thunder damage equal to 1d6 + your Spell Casting modifier and creatures of your choice within 5 feet of the target take thunder damage equal to your Spell Casting modifier.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
