Customizing Merchant Inventories

Merchant inventories can be customized by editing the text files in: BepInEx/config/MerchantNPCs/

Each merchant type has its own file:

  • meadows.txt
  • blackforest.txt
  • swamp.txt
  • mountain.txt
  • plains.txt
  • mistlands.txt
  • ashlands.txt
  • deepnorth.txt

File Format

Each line in the file represents one item with the following format:

ItemName:BuyPrice

Example:

Iron:30
IronNails:8

Item Properties

  • ItemName: The internal name of the item (e.g., "Iron", "IronNails")
  • BuyPrice: How much the item costs to buy

Sell prices are automatically set to half of the buy price.

Customizing Merchant Build Costs

You can customize the resource requirements for building each merchant by editing the configuration file at: BepInEx/config/ruijven.merchantnpcs.cfg

The configuration file is automatically generated the first time you run the game with the mod installed.

Configuration Format

The configuration file is organized into sections for each merchant type:

[Meadows Merchant]
Resource1Type=Wood
Resource1Amount=50
Resource2Type=Stone
Resource2Amount=50
Resource3Type=Flint
Resource3Amount=25

[Black Forest Merchant]
Resource1Type=RoundLog
Resource1Amount=20
Resource2Type=TrollHide
Resource2Amount=10
Resource3Type=Copper
Resource3Amount=10
Resource4Type=TrophyEikthyr
Resource4Amount=1

Customization Options

For each merchant, you can:

  1. Change Resource Types: Modify what materials are needed to build each merchant by changing the ResourceXType values
  2. Adjust Resource Amounts: Change how much of each material is required by modifying the ResourceXAmount values
  3. Add or Remove Requirements: You can set an amount to 0 to effectively remove a requirement

Item Type Names

When changing resource types, you must use the internal item name. Some common examples:

  • Wood - Regular wood
  • ElderBark - Ancient bark
  • TrophyTheElder - Elder trophy

You can adjust the values to make merchants easier or harder to build based on your preferences. For example, setting Resource1Amount=10 would reduce the wood requirement for the Meadows Merchant from 50 to 10.

Building Merchants
  1. Craft a hammer if you don't have one
  2. Open the build menu (right-click with hammer)
  3. Navigate to the "Merchants" tab
  4. Select a merchant type (you'll only see merchants you can build based on your progression)
  5. Place the merchant in your base
  6. Interact with the merchant to open the trading interface
Game Progression

The mod is designed to follow Valheim's natural progression:

  1. Start with the Meadows Merchant (available from the beginning)
  2. Defeat Eikthyr to unlock the Black Forest Merchant
  3. Defeat The Elder to unlock the Swamp Merchant
  4. Defeat Bonemass to unlock the Mountain Merchant
  5. Defeat Moder to unlock the Plains Merchant
