Eldritch Ammunition

Prerequisite: Warlock, Magic Stone cantrip. 

You mastered the ability to magically charge certain objects with your eldritch power.

You can use an action to cast a modified version of the magic stone cantrip to charge up to five objects (including arrows and bolts) with eldritch power. A creature can use its action to objects to thrown or shoot this projectile. On a hit, this object deals 1D10 + your spellcasting modifier of force damage. The Eldritch power remains on the object until the next dawn. After you used this feature, you cannot use it again until the next dawn.
