Sapphire Nightmare Blade

Diamond Mind (Strike)
Level: Swordsage 1, Warblade 1
Initiation Action: 1 Standard Action
Range: Melee Attack
Target: One Creature

You study your opponent for a brief moment, watching his defensive maneuvers and making a strike timed to take advantage of a lull in his vigilance.

You make a Concentration check against the target's AC. If you succeed, the target takes an extra 1d6 damage and is flat-footed vs your attack. If you fail, you take a -2 penalty on the attack.
