Sniper

Sniper [General] Given a good position, you’re able to make accurate shots from extreme distances. Prerequisite: Dex 13, Point Blank Shot, Far Shot, base attack bonus +8 Benefit: When using a crossbow in the prone position or a position where you can rest or mount your weapon on a supporting surface (such as resting it on a castle's crenelation), the range increment of your crossbow increases by one half its normal range. This stacks with the benefit granted by the Far Shot feat, effectively giving you double the crossbow’s listed range increment. Further, the distance to which you can make sneak attacks with a crossbow increases to 45ft. Normal: Ranged sneak attacks may only be made within 30ft. of a target.
