Treasure Isles is a Drowned World Biome presented by the large Ocean theme. It exists in any Drowned World Adventure Portals and can appear in small patches or massive chunks of land. The only obtainable item that is exclusive to this biome are Water Gem Boxes.
This biome consists of a large body of Water (with the exception of the Lairs/Dungeons and several islands and merchant ships) so players will need a Boat or Wings to make travel in this Biome easier since it is comprised mostly of islands and Water. This biome gives off as a vast Ocean filled with Pirates, Crabs, and Sharkmen that dwell within the biome.
