Sure-footed Steed [Active]

(Rule)
Description: If the RIder would be knocked Prone whilst riding Brego, and Brego is not slain as a result of the effect causing the Rider to be knocked Prone, then before becoming a Separated Mount the Rider may roll a D6. On a 6, the Rider is not knocked Prone and stays mounted upon Brego. The Rider may use Might to improve this roll. The Rider may be either Aragorn or Théodred.
