\r\n\r\n<\/div> \r\n \r\nThe **Ocean Trench** is a high-level dungeon with an underwater theme. This dungeon is for high-level players (Suggested Level: 20). \r\n\r\nThe most important factor of difficulty is that players **need oxygen**. An **oxygen counter** gradually goes down until the screen flashes red, which is when players start losing health very quickly. To refill oxygen, players must stand on top of bubble vents that refill the oxygen counter.\r\n\r\nThe entrance to the Ocean Trench is dropped from the [Hermit God](\/wiki\/hermit-god) at a guaranteed rate.\r\n
Key<\/h4>\r\n\r\n The [Ocean Trench Key](\/wiki\/dungeon-keys) is available in the Nexus for 200 [Realm Gold](\/wiki\/realm-gold).\r\n
Guide<\/h4>\r\n\r\nSee the [Ocean Trench Guide](\/wiki\/ocean-trench-guide) for a complete walk-through on the dungeon and all its enemies.\r\n
