Inertial Focus (3.5e Maneuver)

You realize there is more to your body than what is visible, and by positioning your spiritual body, you are able to defy mass and inertia.

You gain the ability to stand upon liquids as if they were solid surfaces, and are able to move up to twice your normal speed upon them (though if you move faster, you fall through). As a swift action you may adjust your weight from anywhere from 1/8th to 8 times your original weight, gaining a +4 bonus to stability against ability checks made to resist being bull rushed or tripped when standing on the ground (but not when climbing, flying, riding, or otherwise not standing firmly on the ground).

Your weight-shifting abilities allow you to endure falling damage better. For every rank in concentration you have, you may ignore up to 10 ft. of fall damage, up to becoming immune to fall damage at 20 ranks.
