Scatter

Scatter weapons are capable of devastating multiple enemies at once.

When you take the attack action and successfully hit a creature with a Scatter weapon, measure the weapon's Scatter range from the square (or point of impact) that the target you hit occupies.

All creatures other than the original target that fall within the weapon's Scatter range must make a Dexterity saving throw against your scatter DC. Upon a failed save, they take damage equal to the ability modifier you used to hit with the weapon (minimum of 1). Damage dealt this way is the same type as the weapon you hit with.

Scatter Save DC = 8 + your proficiency bonus + the ability score modifier that you use to determine the damage for this weapon.

A weapon's Scatter range and shape are mentioned in its statistics. For example, a Flame Bellows has a range of 15 feet and a scatter range of 15 feet. This means that the weapon can hit a target within 15 feet, and upon a hit, a 15-feet cone extending beyond the target will determine those hit by the scatter effect, up to a total distance of 30 feet for the attack.
