Level: Swordsage 5 , Warblade 5
Prerequisite: 2 Diamond Mind maneuvers
Initiation Action: 1 standard action
Range: Melee attack
Target: One creature
Duration: 1 minute
Saving throw: Will negates

With a combination of brute force, keen timing, and exacting aim, you force your opponent into an awkward position that ruins his next action.

As part of this maneuver, you make a melee attack. If this attack hits, your target takes normal melee damage and must make a Will save (DC 15 + your Str modifier) or be unable to take any actions for 1 round. The target does not suffer any other drawbacks or penalties. He can still make attacks of opportunity but is unable to take immediate actions until his next turn.

This maneuver has been updated by errata. See Disrupting Blow for details.
