The Runebound behemoth is a large beast with the ability to use all three protection prayers simultaneously. While these prayers are active, it is invulnerable to the corresponding damage (melee, ranged, magic), except Vengeance. Within the boss room are three active power crystals (one for each combat style) that must be deactivated to remove the respective protection prayer for 10 seconds. Players must wait about 30 seconds before they can deactivate each crystal again, meaning that 2 attack styles are advised. The protection prayer(s) currently active will be shown above the behemoth as with normal protection prayers. For example, when all three styles are protected against, the following icon displays: File:Protect from all.png.
