At 6th level he may ignore miss chances from concealment and spells like blur. At 11th level he may make a second shot and his AC penalty is reduced by 1. At 16th level he may fire through effects like Wall of Force or Force Cage and the attacks are ranged touch attacks. At 20th level he may fire a third arrow, he gets an additional +1 bonus on his attack roll, and he no longer receives a penalty to AC.
