The Banner of Bandos is a standard used to show a players devotion towards Bandos. Its cosmetic look will change as the owner completes task sets provided by Murknose. Like all banners, the banner obtains the ability to boost skills for 30 minutes based on the set completed:
Combat boost - temporarily boosts your Attack, Defence, Strength, Ranged and Magic levels by 5.
Skill boost - temporarily boosts one of any non-combat skill excluding Agility by 2.
Exploration boost - temporarily boosts your Agility level by 5.
Other items providing a visible level boost, such as spicy stew or tea in a player-owned house, will not stack with the banner's effects.
