The Ocean Trench is a high-level dungeon with an underwater theme. The dungeon is a source of Potions of Mana, and is the main source of the untiered Coral Huntress UT Set and two pieces of the Slurp Scion Wizard ST Set.
The most important difficulty factor 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 (faster than when you stand in magma or lava, almost -100 hp/sec). To refill oxygen, players must stand on top of bubble vents that refill the oxygen counter. If an oxygen source is not found and your hp reaches 0, you die from “Damage Suffocation”.
The entrance to the Ocean Trench is dropped from the Hermit God at a guaranteed rate.
This dungeon must be completed to earn the ‘Tunnel Rat’ fame bonus.

Mermaids were long thought to be an extinct race, but they still exist in small numbers at the farthest depths of the ocean.
The extreme water pressure in the Ocean Trench kills most wildlife, but mermaids harness it to control the waves above.
When the mermaid population was higher, the Ocean Trench was the grave of many sailors lured to their demise by the singing sirens.
The Ocean Trench Key is available in the Nexus for 150 .
See the Ocean Trench Guide for a complete walk-through on the dungeon and all its enemies.
The dungeon primarily consists of medium to large circular rooms linked by narrow hallways. Air vents will be scattered in each room and will allow players to refill their oxygen. Each room has purple floor tiles and dark purple walls. Decorative coral and seaweed can also be found, although larger, destructible coral obstacles will be located in the hallways.
Thessal is currently the only boss to have a possible chance for extra loot after defeating her. Randomly, Thessal will crumple over the loot bag and ask the adventurers, “Is King Alexander alive?”. If you respond correctly with ”He lives and reigns and conquers the world,” she will thank you and spawn 3 Coral Gifts. If enough time has passed without saying the correct phrase, she will shout “You speak LIES!” and unleash a storm of projectiles before dying and dropping no loot. If you are standing on her when the phrase is not said within a few seconds, you will die.

If you are soloing, be cautious around the Sea Mare, since getting caught by the paralyzing bullets it shoots can usually mean death or nexusing, since there is no one safe to teleport to.
There are always 11 rooms between the start room and the boss room, not counting either.
In most Trenches with a medium-large group of people, 2 or 3 players will rush the dungeon while the rest of the group stays at the start. Once the rushers reach Thessal, the group at the start will teleport to the rushers. Previously, If one missed the TP, have not maxed att/dex, or/and played on a low DPS class, it was very difficult to get soulbound damage on Thessal because she would often die in less than five seconds. However, as of Release X12, Thessal received HP scaling and the soulbound loot damage threshold was lowered to make it easier for more players to receive loot.
With the addition of the Oceanic Apparel ST robe as a drop from Fishman Warriors, there is now a greater incentive to clear the dungeon instead of simply waiting at the spawn room for rushers to reach the boss.
