Wind Step (3.5e Martial Artist Maneuver)
From D&D Wiki
Mobility is the seed of control on any battlefield.
Level: Active 1
Type: Action (Movement)
Description: You circle around your opponent with several extremely fast steps. If he fails a Reflex save against a DC of 10 + ½ your initiator level + your Intelligence modifier, you are effectively flanking him by yourself. Class features like improved uncanny dodge also protect against the flanking effect of this maneuver, unless your initiator level is at least four higher than the level(s) of the class(es) that grant the opponent improved uncanny dodge. While using wind step, you may end your turn in any one of the squares adjacent to your opponent's square.
