Core Keeper: How to get NPC merchants to live in your base
Core Keeper NPC houses let merchants live with you, but only if you build them proper bedrooms.

Core Keeper NPC houses need to be built properly if you want the friendly little merchants to live at your base. As you explore the underworld of Core Keeper you’ll find powerful boss monsters, and when you defeat them you’ll gain access to special items that can be used to summon wandering merchants to come live with you.
There are three known NPCs merchants in Core Keeper, and two of them need houses: the Slime Merchant and the Caveling Merchant (the third, the Spirit Merchant, does not need a house—more on this below). Having merchants close by your base is useful because they’ll buy any valuables you find in exchange for ancient coins and sell items you may need. It’s also nice just to have a little company at your base, especially if you’re playing solo.
There are a few rules you need to follow to properly build a house for an NPC merchant and specific items you need to place in their rooms or they won’t move in. Below, we’ll go over the different merchants in Core Keeper and how to lure them into becoming your roommates.

Here’s what you’ll need for each merchant you want to occupy your base:
Note thatthe room should be no bigger than 8x8or the merchant won’t move in. Each merchant’s room should also havea wooden door—at the moment, there appears to be a bug so stone doors will prevent the merchant from moving in.
You will also need to placea bedin the room for the merchant. Once placed,players should not sleep in this bedor the merchant will begin wandering away from your base. If you do sleep in the bed, remove it and replace it, which will draw the merchant back.
Finally, you’ll need to place each merchant’ssummoning itemin their room (except the Spirit Merchant, which can be placed anywhere). The items are:

Once you’ve built the room and placed the bed and summoning item on the floor (not on a pedestal), travel away from your base for a few seconds. Once you’ve moved a few screens away from your base, return and the merchant will appear in their room.
Note: With the door closed, the merchant should remain in their room. With the door open, they may leave the room and wander around nearby. Don’t worry, they won’t completely leave the area and will stay pretty close to their room.

You gain access to the merchants by defeating Core Keeper’s first three bosses. Here’s each merchant, the boss you need to defeat, their summoning item, and what they sell. Note that merchants initially do not have every item in stock and their inventories may increase as you progress.
Spirit Merchant
The Spirit Merchant
The Spirit Merchant is a bit different. After defeating the Hive Mother, you can craft the Ancient Hologram Pod at the Hive Mother statue at the Core. It does not need a room or a bed (because the Spirit Merchant is a hologram).
The Ancient Hologram Pod is a workbench that summons the Spirit Merchant, allowing you to craft additional items.

He’s also a fan of offbeat simulation games, mods, and ignoring storylines in RPGs so he can make up his own.
