Burst

When you would make a ranged weapon attack with a weapon with this property, you can instead spray a 10-foot-cube area within range with shots, consuming ammunition equal to the burst number. Each creature in the area must make a Dexterity saving throw (DC = 8 + your bonus to attacks with the weapon) or take the weapon's normal damage. Before you use this property, you can declare one creature that would be affected by it. If the creature fails its save, in addition to the weapon's normal damage, it is subjected to any additional effects that would occur on a hit. If you would have advantage on your attack roll, the creature instead has disadvantage on their saving throw, and if you would have disadvantage on your attack roll, the creature instead has advantage on their saving throw.
