Irresistible Mountain Strike

Stone Dragon (Strike)
Level: Crusader 6, swordsage 6, warblade 6
Initiation Action: 1 standard action
Range: Melee attack
Target: One creature
Duration: 1 round
Saving Throw: Fortitude partial

You slam your weapon into your foe with irresistible force. He can barely move as he struggles to marshal his defenses against you.

As part of this maneuver, you make a single melee attack. This attack deals an extra 4d6 points of damage. A creature hit by this strike must also make a successful Fortitude save (DC 16 + your Str modifier) or be unable to take a standard action for 1 round. It can otherwise act as normal. A creature that successfully saves still takes the extra damage.
