As an action, you can expend 10 pieces of a Burst Fire weapon's ammunition to spray shots in a 10-foot Cube within the weapon's normal range. Each creature in that area must succeed on a DC 15 Dexterity saving throw or take damage. Roll the weapon's damage once, and apply it to each creature that failed the save.
