Void Step (Feat)

Your ability to maneuver in a crowded battlefield is unrivaled.

Prerequisites: Level 21, Dex 27, Blinding Speed (Feat)

Benefit: Once per encounter you may move up to your base speed as a swift action. This may be combined with a normal move action. When under the effects of a haste spell or similar ability such as Blinding Speed (Feat), the movement taken as a swift action does not provoke attacks of opportunity for moving through threatened squares.
