Threats of the Galaxy, page 127.
You are able to react to incoming attacks, using your mount or speeder bike to absorb attacks against you.
Prerequisites: Trained in the Pilot or Ride skill.
Benefit: When riding a beast as a mount or on a speeder bike (as a passenger or a pilot), once per encounter you can redirect an attack made against you at your mount or vehicle instead. The decision to redirect the attack is made after the result of the attack roll is determined but before damage or other effects are resolved.
