Greater Flurry

Expanded description
At 11th level, the Flurry of blows ability expands further by unlocking Greater Flurry which gives the monk two additional attacks per round instead of just one. The monk must be using Flurry of Blows and using unarmed strikes or his special monk weapons (kama, nunchaku, quarterstaff, sai, shuriken, and siangham).
