Tips and Misc

To get to the quest entrance:

Approaching from the east, head north of quest entrance on your map. You will see a ziggurat (the entry is at the top of that). Running north from that is a fence line (that you cannot cross), and just east of where that fence meets the base of the ziggurat is the start of a steep fenced path that winds clockwise up to the quest entrance.
There is a rest/resurrection shrine at the top, where you enter the quest.

Underwater Action items are recommended. But you can get through with -8.5 swimming without any water breathing items or spells.
If you want a breakables bonus, try to break breakables before you flip the lever; after, many will be underwater and unbreakable. There are at least 36 before the lever.
There are seven captives to rescue.
After the barrier is lowered, a waterfall appears at the top of the ladder. The Dungeon Master will tell you it is "impossible" to go against the current, but with Underwater Action and a modified swim score as low as 10, it is indeed possible. Doing so is hardly necessary – the path 'forward' from the lever loops back around – but backtracking to the most recent small chest allows you to bypass several sonic traps.
Underwater sonic traps are marked with glowing white spiral drawings on the walls; swim below those to avoid the traps. Be cautious of your party members – some of the traps are oriented to hit everyone behind the person who triggers them, so being careless (or following too closely behind someone who is careless) can get you hit.
There is a collectable in the waterfall-nook south of the second rest shrine – the first room where you meet water elementals. It is prohibitively difficult to reach the nook directly unless your Jump exceeds 34; instead, proceed to the next room, defeat the second group of elementals, then turn around. Facing back the way you came, there is debris on the right-hand side; jump on that, then jump across to the other side. You should be able to obtain the collectable without nearly as much difficulty.
Generous XP for finishing the optional treasure guardian.
- The optional treasure guardian is a Gelatinous Cube with a chest inside of it, and you want the key inside that chest.
- You cannot damage the guardian until all of the runes at the bottom of the cavern are turned off by running over them. Do it quickly because before long air jets will be blowing throughout the caverns (above and below) that will blow you into the jello monster and several nasty traps at the bottom.
- Once you've turned off all the runes, one tactic to run to the center to finish the fight to avoid the air jets blowing you into the traps and the guardian.
- Open the chest it drops, grab the key, open the treasure cage, loot the chest.

Notes: It may be possible to get kill bonuses by farming the respawning sahuagin mage and water elementals in the room with Foxpaw, after flooding the area; 81 kills was not enough. It may also be possible to stealth into the boss room and open the door to the treasure room before killing Slomnuc for additional kills.

Loot

Chests: 5 (Tip: Both small chests can be accessed early with use of Abundant Step or similar abilities)
- Small Chest in the room with the first Rest Shrine, accessible after the flood.
- Small Chest in a passage north-west of the first shrine room, accessible after the flood.
- Locked Chest behind a secret door (the door located behind the underwater lever near the Sogshadow Moss Patch that gives water breathing).
