Description: Your skill with a blade seems almost magical, lending you the grace of the ethereal fey.

Prerequisites:

Your fey blood allows you to move with the fluidity of the wind. In any round in which you make a single attack with a longsword, you gain +10 feet to your base movement rate. Also, during this round you benefit from a +1 dodge bonus to Armour Class, as long as you move at least 30 feet in the round. You only gain this bonus if you are wearing light or no armor.
