The Saradomin banner is the standard of Team Saradomin in the Castle Wars minigame, in which players on Team Saradomin must defend the Saradomin flag while players on Team Zamorak attempt to capture it and return it to their base to score points. The flag can be passed to another player if it is dropped. It can be bought from the Castle Wars Ticket Exchange shop, owned by Lanthus for 100 castle wars tickets.
The Saradomin banner is a large blue standard bearing the symbol of Saradomin, attached to a long wooden pole. It plays a key role in Castle Wars. It is kept on the top floor of the Saradomin base. Its counterpart in the opposing team is the Zamorak banner.
If captured, the player doing so will automatically switch his current weapon and shield with the standard, which is held with both hands. Players can attack with the standard, but it is very weak weapon without any accuracy or strength bonuses. If a player with the standard is killed, the standard will be dropped on the ground, allowing it to be taken by members of either team.
