Back on your horses
(Rule)Description: At the end of a friendly Infantry Hero model's Move (with the exception of Gimli), if they are in base contact with a friendly Cavalry Warrior model who is not Engaged in Combat, then the Warrior may give the Hero their horse. Replace the Warrior model with a suitable dismount, and replace the Hero with the mounted version of them. The Warrior will be placed in the same place as the Hero was, and vice versa. If the Hero would normally have a named horse (such as Snowmane or Brego) then they will only count as riding a standard horse after using this rule.
