You spin your staff in a blur of motion, knocking incoming projectiles aside and keeping nearby enemies at bay.
Prerequisite: Monk, Flurry of Blows class feature
Benefit: When you use your flurry of blows power while you are wielding a quarterstaff, you gain partial cover from ranged attacks and area attacks until the end of your next turn. In addition, you do not grant combat advantage for being flanked until the end of your next turn.
