The dungeon on Mos Le'harmless is home to the slayer monster the Cave Horror. When entering the dungeon, be sure to have a light source, and if you plan on killing cave horrors, be sure to bring a witchwood icon as well. In the northeast corner of the dungeon are two ladders which lead to the two small islands with teak and mahogany trees north of Mos Le'harmless.
