Emerald Razor(Tome of Battle: The Book of Nine Swords, p. 63)
Diamond Mind (Strike)
Level: Swordsage 2 (One Diamond Mind maneuver), Warblade 2 (One Diamond Mind maneuver),
Casting Time: 1 standard action
Range: Melee attack
Target: One creature
You stare at your enemy, studying his every move. You mentally probe his defenses in search of a weakness. A lesser warrior could spent long minutes pondering this problem, but you see an opening and seize upon it in an instant.
Your understanding of combat, your keenly honed mind, and your capability to read your opponents make you a deadly combatant. When you focus your mind, even the most elusive opponent becomes an easy target.
As part of this maneuver, make a single melee attack against an opponent. This is a touch attack rather than a standard melee attack. If you hit, you deal normal melee damage.
