Air Bullet

As a verbal component needed to cast this spell you take a deep breath, when you exhale you let out a blast of pressurized air that takes form of a projectile.

Make a ranged attack against the target of this spell (this spell can target objects and creatures). On a hit the target suffers 1d6 bludgeoning damage (damage done by this spell is considered magical when you reach level 5). Additionally, after using an action to cast this spell you can use your bonus action to cast it again with no components needed (using the same breath of air). You can direct the projectiles at the same target or at different ones. Make a separate attack roll for each projectile.

The spell creates more than one projectile when you reach higher levels: two projectiles at 5th level, three projectiles at 11th level, and four projectiles at 17th level.
