Trick Shot

You enchant your ammunition or thrown weapon, to enable it to ricochet the next time you use it.  The next time you make a ranged weapon attack against a creature before the spell ends, you may nominate a second target within 20 feet of them.  You do not need to be able to see the second target, but you must be aware of its location.  Make a ranged weapon attack against the first target as normal.  If you hit, that target takes half the attack's damage and the ammunition rebounds towards the second target.  Make a ranged spell attack with advantage against the second target.  If this attack hits, the target takes the normal weapon damage, and you get a bonus to the damage equal to your spellcasting ability modifier.

If you miss the first target, the ammunition or weapon rebounds 20 feet from its space in a random direction.  If it would pass through a creature's space, make a ranged spell attack with disadvantage against that creature.  On a hit, the creature takes half of the attack's normal damage.

Hit or miss, once the ammunition has rebounded, the spell ends.

At Higher Levels: If you cast this spell using a spell slot of 3rd level or higher, the ammunition may rebound off one additional creature for each slot level higher than 2nd.  Each target the attack rebounds off takes half the attack damage, and each new target must be within 20 feet of the previous one.
