Merchants are friendly creatures who serve as shopkeepers to the player. A merchant will move in when their respective spawn item is placed in a habitable room.

Interacting with a merchant will open their shop menu. In the shop menu the player can purchase items with Ancient Coins, or sell items to obtain Ancient Coins. Each merchant has a limited stock of items, and it will take some time (see below) for their shop to refresh after one item is out of stock.

There are a total of 6 merchants and 6 respective spawning items in the game.

Housing requirements

In order for a room to be considered "habitable", the following requirements must be met:

• The room must be fully enclosed with solid walls (doors are considered walls).
• The room must have no more than 64 tiles of floor space (making the maximum possible room size 8×8).
• A Bed is placed anywhere inside. It can be shared as the player's spawn point.
• At least one floor tile is free of furniture (making the minimum possible room size 2x2).

Neither lighting or a door are technically needed for a room to be considered valid.

Once all room requirements are met, and the merchant does not have an existing Bed set as their spawn point, they will arrive immediately.

Notes

• Merchants will restock once every 25–35 minutes. The exact time is random, and different for every merchant.
  • Activating the Ghorm Statue, Malugaz Statue, The Core or defeating the Core Commander (the first time) will immediately trigger a restock for all merchants.
  • Alternatively the merchants will restock when loading a save. Save & Exit again to restock as many times as necessary.
