Prerequisites: Dodge, Dex 13
Benefit: You may move up to one-half your base speed as a swift action.
Special: Dash can be used in place of Mobility to qualify for a feat, prestige class, or other special ability.
The movement from dash is treated as normal movement for all intents and purposes; thus, you cannot dash in the same round that you take a 5' step and movement when dashing provokes attacks of opportunity. You cannot combine a dash with a Jump or Climb check of any kind, although you can combine it with Tumble checks.
