Core Powers

Force Speed was a Force power that allowed the user to maintain sprinting speeds (even moving in awkward directions like backwards) for a brief time. Greater aptitude granted greater boosts to speed and/or greater duration.

The increased speed of the Jedi enabled him to see the world and the entities around him in slow motion. This allowed the Jedi to dodge attacks easier, and attack quicker with greater accuracy.

The duration and the amount of speed were subject to the user's skill in the Force. With sufficient skill, one could actually run on vertical surfaces for brief periods of time.
