Iron Heart (Strike)

Level: ; Warblade 4
Prerequisite: Two Iron Heart maneuvers
Casting Time: 1 standard action
Range: Melee attack
Target: All adjacent opponents

Your weapon becomes a blur of motion as you swing it in a tight arc over your head. Once you build up enough speed, you explode into a sweeping attack that chops into the enemies around you.

When you initiate this strike, you make a melee attack against every opponent adjacent to you. Resolve each attack separately. You gain a +2 bonus on each of these attacks, which are otherwise made at your highest attack bonus.
