Explosive Bolt

This magical bolt may be fired from any bow or
crossbow. When the bolt reaches the end of its
trajectory, in addition to the ordinary damage
dealt by the ranged weapon, all creatures within
10 feet must succeed on a DC 15 Dexterity saving
throw. A target suffers 1d6 piercing damage and
1d6 fire damage on a failed saved, or half as much
damage on a successful one. The fire ignites
flammable objects in the area that aren't being
worn or carried.
