Adamantine Hurricane p. 66
In a blur of motion, you make a short,twisting leap in the air. As you turn, your weapon flashes through the enemies around you like a blazing comet. As you drop back to the ground in your fighting stance, your enemies crumple to the ground around you.
You sweep your weapon in a circle around you, striking out at nearby enemies. You strike with the speed and ferocity of a lightning bolt, forcing your enemies to rely on their reflexes for protection rather than their armor and shields. You make two melee attacks against each adjacent opponent you threaten when you initiate this maneuver. You receive a +4 bonus on each of these attacks, which are otherwise made with your highest attack bonus.
