Ricocheting Shot

As you have great reflexes, you learnt how to make your shots bounce around as you please. Therefore, you gain the following abilities:

Your dexterity score increases by 1, to a maximum of 20.
When you make a ranged weapon attack, you may use this feat to ricochet your attack to a different target as long as it is within 5 feat of your previous target. On each ricochet, make a new ranged weapon attack roll ( with proficiency bonuses included) on the new target with the following caveats:
For each target the attack has hit, the AC of the next target increases by 4 (1d8), which stacks with each subsequence target.
Moreover, for each target the attack has hit, the damage of the subsequent attack decreases by 1, which also stacks with each subsequent target.

For example, when the attack ricochet the first time, the AC of the target enemy will increase by 4 ( 1d8) and the damage decreases by 1. For the second ricochet, the target AC increases by 8 ( 2d8) and the attack decreases by 2. 

This attack will continue until the attack misses or the attack has been nullified.

This feat can only be used once per turn.
