Stone Vise

Iron heart (Strike)
Crusader 2, swordsage 2, warblade 2
Initiation Action: 1 standard action
Range: Melee attack
Target: Creature struck
Duration: 1 round
Saving throw: Fortitude partial

By making a powerful, focused blow, you leave your opponent unable to move. The crushing weight of your blow forces it to waste a precious moment regaining its footing.

As part of this maneuver, you make a single melee attack. This attack deals an extra 1d6 points of damage. If the creature hit is standing on the ground, your attack also drops the target's speed to 0 feet (for all movement capabilities) for 1 round. It can otherwise act normally.

A successful Fortitude save (DC 12+your Str modifier) by the creature struk negates the immobilization, but not the extra damage.

This maneuver functions only against opponents standing on the ground. A flying creature or a levitating target need not save against the speed reduction effect, but still takes the extra damage.
