Mind Strike(Tome of Battle: The Book of Nine Swords, p. 64)
Diamond Mind (Strike)
Level: Swordsage 4 (Two Diamond Mind maneuvers), Warblade 4 (Two Diamond Mind maneuvers),
Casting Time: 1 standard action
Range: Melee attack
Target: One creature
Saving Throw: Will negates
You strike your opponent?s head, rattling his senses and causing him to lose focus.
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, your target must make a Will save (DC 14 + your Str modifier) or take 1d4 points of Wisdom damage. The target ignores the Wisdom damage on a successful save but still takes weapon damage normally.
