The icelords are icy beings that live inside the iceberg, and were found when Pescaling Pax moved much of the penguin population to the iceberg to prepare for the invasion of Gielinor. Some icelords enjoy hurling large icicles at their enemies, while others prefer to use their four arms to pummel them into submission. Pescaling Pax intends to use these as a strike force when they do invade the mainland.
Icelords are encountered during the Cold War quest. They are in a cage on the penguin's iceberg that is explored during the quest. After the quest is finished, the monsters can be accessed by once again entering a crack in the ice, then re-entering the cage.
Inside the cage, there are three icelords that use melee, and one wielding icicles that uses ranged. They are weak to magic attacks, so it is recommended to use the best magic spell available to the player.
They can be slain in place of ice warriors for the purposes of completing a Slayer task. They have slightly more hitpoints than ice warriors but are notably weaker in both defensive and offensive stats, making them higher experience per hour, though do not drop any loot aside from bones.
Killing an icelord will award you with a bonus 40 Attack experience during the Cold War quest.
