What the achievement asks
Find and open all the Sturdy Chests hidden in Sidestreet Sluice. 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
Sidestreet Sluice 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 | 33.46 73.12 | On the lower platform under a tank, above the slime pool |
| 2 | 77.46 39.48 | On a ledge, just after a room |
| 3 | 61.79 65.89 | Behind a large tank, past Windle Snapkrank |
| 4 | 74.54 73.98 | On the right as you enter the treasure room |
The stories that may hide a chest
If a chest will not appear, the delve's story variants are All That Glitters, Mr. DELVER and Teleporter Tantrums. Come back on a day when a different one is running.
