What the achievement asks
Find and open all the Sturdy Chests hidden in Excavation Site 9. Five points, account-wide.
How Sturdy Chests work
Every delve hides four or five Sturdy Chests. They are one-time treasures: once looted, that chest is done for your account for good, so there is nothing to farm and no respawn to wait on.
Most people collect the whole set in a single run, but not always. Some chests only appear during certain story variants. If you have swept the delve and one coordinate is stubbornly empty, that is the reason, and the answer is to come back on a day when a different story is running rather than to search harder.
The tier makes no difference here. Run the delve at whatever difficulty you find comfortable, ignore the objective, and walk the chest list.
Getting there
Excavation Site 9 is in Undermine. Delves are permanent, labelled icons on the zone map, so there is no coordinate to hunt for: open the map and click the delve.
The chests, inside the delve
These coordinates are inside the delve, on its own map, not on the zone map. Paste them once you are in.
| Chest | Coordinates | Note |
|---|---|---|
| 1 | 73.0 40.0 | Up beside the stone head, jump the tables |
| 2 | 57.0 47.0 | Behind the big root before the checkpoint |
| 3 | 50.0 61.0 | At the side of the pond |
| 4 | 33.0 58.0 | Between the two tents |
The stories that may hide a chest
If a chest will not appear, the delve's story variants are Lost Excavators, Black Blood Profits and Rowdy Rifts. Come back on a day when a different one is running.
