Warmaster of Bandos is a title that was unlocked by participating in The Bird and the Beast world event. It could be obtained after doing certain activities for the Bandosian faction. It was randomly rewarded to players for destroying an Armadylean caravan, building structures, and killing opposing players. In order to qualify for the title, a player had to defeat a minimum of 20 enemy players, build at least one structure, destroy a caravan, or destroy an enemy structure. Players with this title were not allowed to obtain the Vanguard of Armadyl title and vice versa. Both titles would get re-locked whenever a player switched factions, making it impossible to own both.
This title changes according to the language of the server on which RuneScape is played, as shown below:
||[Name], Kriegsherr des Bandos / Kriegsherrin des Bandos
