4th-level / Diamond Mind
As a warrior who fights with your mind as well as your brawn, you know that attacking a foe’s senses is just as valuable as sapping his strength. With this attack, you leave an opponent befuddled and vulnerable. As part of this maneuver, make a melee attack. If this attack hits, you deal normal damage and the target looses concentration on any spells. Additonally the target can't use its action on its next turn.
