\r\n\r\n\r\n\r\n\r\n<\/div> \r\n \r\nThe **Ocean Trench** is a hard and high level dungeon with an underwater theme. This dungeon is for high leveled and experienced players (Suggested Level: 20 and **Defense** Maxed). Enemies have **Strong Attacks** and a lot of health and the boss does **High Damage** per bullet.\r\nThe most important factor of difficulty is that players **need oxygen**.\r\nAn **oxygen counter** gradually goes down until the screen flashes red, which is when characters start losing health very quickly. To refill the oxygen, characters must stand on top of certain spots of bubbles that refill the oxygen counter.\r\n\r\nThe entrance to the Ocean Trench is dropped from [Hermit God](\/wiki\/hermit-god).\r\n
