Self Bow Expert

Your experience with Short Bows and Longbows has made you expert in their use in combat.  If an enemy moves to a position where they can perform a melee attack against you, you may make an opportunity attack against them using either a Short Bow or a Longbow, then move up to half of your movement.  The opportunity attack does not accrue disadvantage if the target is within five feet of you, and nor does the movement provoke opportunity attacks.
