Piercing shot

You've learned to put the weight of a weapons draw strength to your advantage. You gain the following benefits:

• On your turn, when you score a critical hit with a ranged weapon or reduce a creature to 0 hit points with one, you can make one ranged weapon attack as a bonus action to a target behind your initial target.
• If you so choose you can subtract your + modifier to hit (min of 0 - max of your +) and add it to the damage, this is effected by critical hits.
