Explode
Prerequisites Level 5 Craftsman, Fire Damage, Masterwork Ranged Weapon
When you take the Attack action, you can replace one of your ranged attacks with an explosion from this weapon’s projectile. This explosion is a 5-foot-radius Sphere centered on a point you choose within the weapon’s normal range. Each creature within the Sphere makes a Dexterity saving throw (DC 8 plus your Strength or Dexterity modifier and your Proficiency Bonus). On a failed save, a creature takes the weapon’s damage, but don’t add your ability modifier to that damage unless that modifier is negative. On a successful save, a creature takes half as much damage. You can create an explosion only once per turn.
