Corvin's Explosive Arrow

The next time you make a ranged weapon attack during the spell’s duration, the weapon’s ammunition, or the weapon itself if it’s a thrown weapon, detonates on impact.  Each creature within 5 feet of the blast must make a Dexterity saving throw. On a failed save, the creature takes 4d8 force damage, and is pushed 5 feet away from the blast and knocked prone.  On a successful save, the creature takes half as much damage and is not pushed or knocked prone.

The ammunition or weapon is destroyed as a result of the spell. 

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
