Explosive Cannonball

A creature hit by this ammunition takes the weapon's normal damage, and each creature within 10 feet of it must succeed on a Dexterity saving throw (DC 8 plus your Strength modifier and your Proficiency Bonus) or take 2d8 Fire damage. On a miss, the ammunition fails to detonate. Once it hits a target, the ammunition is destroyed. Explosive Cannonballs are typically stored in a Sack (bought separately).
