Chaos Elemental - The RuneScape Wiki

The Chaos Elemental is a boss found west of Rogues' Castle deep in the Wilderness, and one of three bosses available to free-to-play players. It is one of the strongest monsters in the Wilderness, overtaking the King Black Dragon, which held the title for four years. The Chaos Elemental held the title for two years and seven months before the introduction of the Corporeal Beast. With an update in 2017, it is now available to free players and is the strongest free-to-play monster.
