Twig's Bombardment

You create 10 small bombs that can quickly be thrown at a creature. When you cast the spell, you can make a ranged spell attack against a creature within 30 feet. On a hit, the target takes fire damage equal to 1d8 + your spellcasting ability modifier. The bombs only last for the duration of the spell.

As a bonus action on your following turns, you can throw and additional bomb to a target within 30ft.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every two slot levels above 2nd.
