Once per game, at the start of any Fight Phase, Aragorn can use this special rule so long as he is alive and on the battlefield. If he does, then friendly non-Eagle models within 6" of Aragorn gain a bonus of +1 Fight Value and may re-roll To Wound rolls of a natural 1 when making Strikes until the end of the turn. This is treated as an Active ability belonging to Aragorn.
Gandalf may re-roll a single D6 in any Casting Rolls he makes.
So long as Aragorn is alive and on the battlefield, friendly models automatically pass any Courage Tests they are required to take.
Friendly Infantry models within 3" of a friendly Hero model gain the Dominant (2) special rule.
