Penetrating

When you would make a ranged weapon attack with a weapon with this property, you can instead attempt to penetrate and hit a creature behind the target, consuming ammunition equal to the penetrating number. Make an attack roll against the initial target. If the attack hits, there is a creature within 15 feet of that creature and directly behind it, and the original attack roll would hit the second creature, it also takes normal weapon damage. Alternatively, you can use this property to fire at a creature through partial cover. When you do so, you reduce the target's cover by one step (from three-quarters to half or half to one-quarter), rather than targeting a second creature.
