On the Operation: Egg Heist map, the Ornate Iron Chest turns up in just one place: the Mountain Sanctum holds the single marked spot, so there is no choosing between locations here. It is a container you open on the map, and finding it means heading to the Sanctum and nowhere else. With only one to track down, there is no risk of missing a second along the way, which keeps the trip simple and leaves you free to head straight for the mark.
Areas with Ornate Iron Chest
| Area | Level | On the map |
|---|---|---|
| Mountain Sanctum | — | 1 |
Opening it gives you a haul worth the detour, so make the Mountain Sanctum your single stop and go straight to the marked point. The walk is short and the payoff sits in good company: when you reach the chest, an Exquisite Relic Chest stands in sight, a Simple Stone Sarcophagus sits nearby, and an Ornate Wooden Chest waits within view too. Clear all four in the one visit and you leave the Sanctum with nothing left to come back for.
