To the bulleted list in “Approaching Beasts”, add a second point:-

If exactly one Knight on the Approach is a Taming Knight, and the number of Taming and Scouting Knights exceeds the number of Attacking Knights, and the Beast has not already been Tamed, then the Beast is Tamed by the Taming Knight: it has the text “Tamed by the Knight called [name].” added to its rule, where “[name]” is the name of the Taming Knight.

To the rule “Beasts”, add:-

If a Beast has been Tamed by a Knight and is not Slain, then that Knight may apply the effects of its Behaviour as a daily action.
