Player workbench

Retrieve the Diamond Trinket from Cape Bonavista's riverbed before planning an oxygen-sensitive dive.

The south-beach cave holds a separate treasure-map route, while the viewpoint-side river holds the named trinket; a money chest cannot close the trinket job.

Why this entry is useful

A three-way Cape Bonavista marker split—river Secret, cave treasure and regular chest—with an air-safe pickup and effect check.

The 151, 586 lead points to the viewpoint-side riverbed, not the cave treasure. Confirm the Secret icon, named trinket and present oxygen effect in your save before relying on it underwater.

Safe first move

From the Cape Bonavista viewpoint, identify the adjoining river, mark the surface exit and inspect the Secret marker near 151, 586 before descending.

Finish line

Diamond Trinket appears by name in inventory, its current oxygen effect is readable, and the river dive ends with enough air to surface safely.

How to use it

Separate the river Secret from the cave and money chests

The Diamond Trinket is a viewpoint-side riverbed Secret. A cave treasure or a regular chest can be collected on the same island without changing the named trinket inventory.

Recovery path

I found a chest, not the trinket

If the pickup yielded a map, money or an unrelated reward, surface and reopen Cape Bonavista's viewpoint-side river marker. If air is short, return to the bank before another descent. Verify the trinket name and current effect rather than relying on the area counter alone.
