Rolling Around at the Speed of Sound (3.5e Maneuver)

You're too slow.

Make a Tumble check as part of movement. The check result is your new base movement speed for the duration if higher (round down to the nearest 5 ft increment). This is added before augmentations to your movement such as haste. This effect lasts for 1 round.

While you are moving under the effect of this maneuver you do not provoke attacks of opportunity for your movement. You ignore difficult terrain and other effects which slow your movement speed (such as solid fog, though you may still take penalties or damage from the effect. You cannot use this to escape if you are immobilized.

This maneuver may be used in overland movement. As long as you take nothing but move actions in a straight line for 1 minute, your speed increases until you are moving at over Mach 1. You create a loud but harmless thundering noise in your passing, crossing up to 2 miles each round. You can cross over liquid surfaces as if they were solid, and make jump checks up to 2000 ft high to cross obstructions. Your reaction time increases to compensate for the higher speed. The maneuver ends once take any action beyond a move action, or if you run into an object in which case you take no damage, but fall prone.

This maneuver is extraordinary, but the overland movement option is a supernatural ability.
