As the sea falls, the important change is not just a smaller water meter: more ground becomes available to inspect. This guide separates named landmarks from collectible treasure, because a large object in the scenery is not automatically something you can pick up or sell.
There is no verified complete item catalog, sale-price list, or depth chart here yet. The reference below covers the landmarks named in the Playgama description and explains how to investigate them without mistaking guesses for game rules.
The three landmarks named by Playgama
| Landmark | What the provider describes | What remains unverified here |
|---|---|---|
| Shipwreck | A wreck exposed as the water falls | Exact exposure point, interactions, and rewards |
| Whale skeleton | Bones revealed farther into draining | Whether individual parts are collectible |
| Sunken city | A submerged settlement exposed with further progress | Entry conditions, objectives, and any item values |
Treat these as exploration targets rather than a guaranteed loot order. The description does not supply a coordinate map or a complete list of objects found around each landmark.
How to inspect newly exposed ground
After making noticeable progress, pause to look at the shore and the route down into the basin. Compare the view with an earlier screenshot. A feature that was visible underwater may now be reachable; a newly visible object may still be too far away to interact with.
Approach an object and watch for an interaction prompt. Record its exact name if the interface supplies one. If nothing appears, it may be scenery, outside interaction range, or dependent on a later objective. Do not assume every chest-shaped or bone-shaped object has a sell value.
For useful notes, capture the ocean name, approximate progress, object label, action prompt, and what changed after interaction. This is stronger evidence than remembering only that something shiny appeared near a wreck.
Treasure selling: keep the versions separate
Mana's own page explicitly describes collecting treasure and selling finds to a merchant. Playgama's page emphasizes water processing and salt-funded equipment. That distinction matters: a merchant instruction from a Mana guide is not automatically a verified Playgama mechanic.
If you cannot find a merchant, first check whether the advice you are following belongs to the other version. We have not verified a Playgama treasure-selling inventory, item rarity system, respawn rule, or reward table, so none is presented as fact here.
Should you stop upgrading to explore?
Use exploration as a short check between progression cycles. If a landmark remains inaccessible, continuing to drain the ocean may be more useful than repeatedly trying the same object. If you receive a clear prompt or objective, follow that instruction rather than an assumed percentage from an unofficial checklist.
For equipment decisions, read the upgrade guide. For the transition beyond the current sea, see new oceans and the plug.
