Ballistic Fingers

You enchant your hands with a shimmering blue light. As long as you're not holding anything with one of the enchanted hands, you can take the Attack action on your turn to fire with your fingers. Make a ranged spell attack against a creature you can see within 90 ft of you.
On a hit, the target takes 2d8 + your spellcasting Ability modifier force damage. If both of your hands are free, you can use your bonus action to fire another shot with the other hand.
You have 10 ammunitions total before you can stop firing.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 and the ammunition count increases by 10 for each slot level above 2nd.
