Fires lvl20 magic arrows:

When you do a normal attack it would instead fire a lvl20 magic arrow. All the benifits of a lvl20 magic arrow applies to your normal attack.
Such as:
-uses no arrows from your quiver
-Converts 20% of your physical damage to magical damage
-Adds 181% to your attack rating
-Damage +20


If you have ever use a Kuko Shakaku and done a normal attack you would know what I am talking about. Except that bow fires explosive arrows.
