Mysteries of the Lost Gold (DLC)
The veil lifts from the mystery of an ancient legend...
Unknown dangers lie on the journey ahead—
The Mysteries of the Lost Gold DLC is a permanently-available version of the limited event of the same name.
Adventure[edit | edit source]
Players during the event explore a hexagonal map to unlock resources and rewards as they follow the characters in Nosta.
Story/Exploration Stages[edit | edit source]
Nosta's map is a hexagonal grid consisting of several stage types: primarily these are Story Stages and Exploration Stages. Each tile costs some amount of supplies to unlock (listed below); tiles which cross "Border Checkpoints" nearly always unlock in pairs, and the cost needs only be paid once for the pair (for example, unlocking Lost Gold Story 01-07 also unlocks Explore Nosta Forest VII for "free").
To change regions on the map, a player may tap the "back" button once to zoom out, then tap any tile in the desired new region.
- Story Stages take the player through the event-exclusive storyline; the story is joined in Act I, then splits apart into four paths for Act II and Act III before rejoining for Act IV. In order to view a story tile, the player must have viewed all story stages that precede that chapter; this means that to view the Act IV story, the player must have finished all four routes for Act II and III.
- Exploration Stages put the player onto a grid-based map where the player must complete map tasks such as defeating a Boss, finding Supply chests, and finding the Exit. In the Beach, Forest, and Mountain exploration stages, one Supply Chest per stage will contain
Universal Part x1, used for upgrading Facilities; all remaining Supply Chests will contain 
Astral Memory x20 and possibly some variety of tile unlock materials.
Beach[edit | edit source]
Since the player starts with 500 of each tile unlock resource, it's possible to unlock all Beach stages immediately; while the player will be short on 
Lumber for the final tile, the game will use this to introduce the Work Order supply system. Note that this tutorial requires completion of previous beach stages -- if it does not appear, go back and complete previous stages. Stories may need to be read in full, and exploration stages may need to be exited properly via the exit tile.
