Description: Your skill with the bow seems almost magical.

Prerequisites:

Your fey blood gives you uncanny skill with a longbow. When you use the attack action or full-attack action with a longbow, you can take a penalty of as much as –5 on your attack roll. You may subtract a corresponding amount from the Damage Reduction of any creature you attack that round with arrows from your bow.
