 * Traps (fixed, some undisarmable)
 * traps=Sonic (do not disable before the you flip the leveler)
 * misc=
 * Underwater Action items are highly recommended.
 * Do your best to break breakables before you flip the lever.
 * 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 are seven captives to rescue.
 * 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.
