Spread Fire

A weapon that has the Spread Fire property can't make a normal attack. It instead sprays a Cone with a length equal to its range (for example, a Blunderbuss with a range of 20 feet will fire in a 20-foot Cone). Each creature in the area must succeed on a Dexterity saving throw (DC equals 8 plus your Dexterity modifier and your Proficiency Bonus) or take the weapon's normal damage.
