Vorpal Arrow

A Vorpal Rabbit appears and stretches into an arrow . Make a ranged spell attack against the target. On a hit, the target takes 4d4 radiant damage immediately and knocks them back 10ft. On a miss, the rabbit kicks off the target for half as much of the initial damage and no damage at the end of its next turn.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage (only initial) increases by 1d4 for each slot level above 2nd and target must succeed Strength DC 13 or be knocked prone by the Rabbit.
