Greatbow Specialist

You are adept at using Greatbows effectively.

• You gain proficiency with Great Bows.
• A Greatbow may only be wielded while planted, one cannot fire the bow while falling, flying, jumping, levitating, or underwater unless the wielder still has some way to plant the weapon properly for firing. This requires the lower arm to be held in place by an object or the ground of some manner. 
• A Greatbow in your hands now exceeds reasonable range to the average archer. Your normal range is 80ft and your long range is 160ft. Your enemies can no longer hinder you by hiding behind half cover as the massive arrows over-penetrate, removing your penalty to-hit target behind half.
