Hurricane Punch (Ex)
Replaces: Stunning Fist
At 1st level, a windstep master gains Hurricane Punch (see page 19) as a bonus feat, even if he does not meet the prerequisites. While using this feat, he doesn’t provoke an attack of opportunity, even if he doesn’t have the Improved Bull Rush feat.
At 4th level, while using the Hurricane Punch feat, the windstep master can bull rush a target up to two size categories larger. At 12th level, the windstep master’s target can be up to three size categories larger. At 20th level, the target can be of any size category.
At 8th level, when the windstep master uses the Hurricane Punch feat to successfully bull rush a creature, he can push the creature back an additional 5 feet. At 16th level, he can push the creature back an additional 10 feet.
This ability replaces stunning fist. Wind Step (Su): At 4th level, the windstep master’s steps become supernaturally light. As a move action, he can use air walk (as per the spell) up to a distance equal to his fast movement bonus. He must reach a solid, level surface able to support his weight by the end of his turn or he falls.
This ability replaces slow fall or the ki power gained at 4th level for an unchained monk.
