Volatile Round

You channel your magic to imbue a bullet with forceful volatility. The next time you hit a creature with a ranged weapon attack using a firearm during the spell’s duration, your weapon's gunshot is much louder, and can be heard from up to 250 feet away, and the attack deals an extra 2d6 force damage as the bullet explodes into magical force. The target must roll a dexterity saving throw. On a failure, they are knocked prone.

When you cast this spell at 2nd level or above, the force damage dealt increases by 1d6 for each level above 1st.
