You hold the power of a small thunderstorm in your hand and transfer it into your weapon. The next weapon attack you make during the spell’s duration deals an extra 8d4 Thunder damage on a hit, or half as much extra damage on a miss. Hit or miss, the energy in the weapon/ammunition explodes forward in a cone. The target and each creature within a 25 foot cone(starting at the target and going directly away from where you attacked) must succeed on a Strength saving throw or be pushed 20 feet away and knocked prone.

At Higher Levels. If you cast this spell using a spell slot of 4th level or higher, the Thunder damage increases by 2d4 for each slot level above 3rd.
