The Ornate Wooden Chest is a container you collect straight off the map, and on the Operation: Egg Heist map there are 13 marked spots to work through. Most of them cluster at the Ancient Altar, which holds 11, with the remaining 2 sitting over at Mountain Sanctum. That split makes the Altar the obvious place to head first, since clearing it puts the vast majority of these pick-ups within reach before you ever need to move on.
Areas with Ornate Wooden Chest
| Area | Level | On the map |
|---|---|---|
| Ancient Altar | — | 11 |
| Mountain Sanctum | — | 2 |
Ride to the nearest stop for the Ancient Altar and make the short walk in, since that puts you on top of the bulk of these spots straight away. While you sweep them, keep an eye out for the extra containers dotted around the same ground: a Simple Iron Chest sits within sight of most, an Exquisite Relic Chest of well over half, and a Simple Stone Sarcophagus of a smaller share. The Ornate Wooden Chest itself is simply picked up off the map as you pass.
