Boom Ammunition

You use ranged ammunition or a thrown weapon to send a beam of crackling energy streaks toward a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 2d6 force damage.

Use additional ammo or duplicate thrown weapon when you reach higher levels: one extra at the 5th level, two extra at the 11th level, and three extra at the 18th level. You can direct the ammo or duplicate thrown weapons at the same target or at different ones. Make a separate attack roll for each.
