Arcane Round

You imbue a mundane round of ammunition with a concentrated dose of a particular magic type, creating an Arcane Round. This Arcane Round deals a type of damage that you choose upon creating the round (acid, cold, fire, force, lightning, necrotic, poison, psychic, radiant, or thunder), dealing 4d12 damage. This counts as a ranged weapon attack, as well as casting a Sorcerer spell.

At higher levels. When you create this Arcane Round using a spell slot of 4th level or higher, the damage increases by 1d12 for each slot level above 3rd.
