Detonate Ammunition

You break a piece of ammunition, causing up to 6 pieces of the same type lodged in creatures to emit a pulse of lightning. Each creature must make a Constitution saving throw. A creature takes 1d6 lightning damage for each piece of ammunition lodged in them on a failed save, or half that on a succesful save. All ammunition detonated is destroyed, and can neither be counted when recovering ammunition, or when casting this spell again.

At higher levels, an extra 1d6 lightning damage is applied for each spell slot level above 1 used, for example casting with a third level spell slot would deal 3d6 lightning damage on a failed save.
