Ritual circles are magical circles which can be found on Uncharted Isles when the player has a contract to sacrifice kelp at them. Untouched Ritual circles emit a bright glow and are marked with Taskmaster icons on the minimap. Sacrificing 3 kelp gives 70 Runecrafting experience and causes the circle to darken and no longer glow.
