🛒 Haldor Trading Overhaul

Transform Haldor into the ultimate merchant with full buy/sell functionality and a personal bank

Buy Tab

Sell Tab

Bank Tab

✨ Features

Browse and buy over 590 items from Haldor, organized by category with real-time search. Sell your unwanted gear directly back to him at 30% of the buy price. Items unlock progressively as you defeat bosses, keeping the economy tied to your progression. All item lists and prices are driven by JSON config files you can edit freely, and a Python script is included to regenerate them from scratch.

The mod has full controller support. Use LB/RB to switch panels, D-Pad or left stick to navigate, A to confirm, X to toggle categories, and B to close. Everything is mapped and works seamlessly alongside the mouse.

🏦 Bank

Haldor acts as your personal banker. Your bank balance funds all purchases. When you buy something, the cost is deducted from the bank, and when you sell, the proceeds go straight in.

To access the bank, open the shop at Haldor and click the Bank tab. Use Deposit to move coins from your inventory into the bank, and Withdraw to take them back out.

🤝 Compatible Mods

Bows Before Hoes by Azumatt — All bows, quivers, and arrows added by this mod are fully supported. Install both mods and they will appear in Haldor's shop automatically. Items are locked behind the same boss progression gates as vanilla items, so they unlock naturally as you play.

Mod Conflict Warning

This mod targets Haldor specifically by prefab name. The custom UI only intercepts interactions with Haldor — all other traders (Hildir, modded trader NPCs) continue to use the vanilla StoreGui as normal.

However, any mod that alters Haldor himself may cause conflicts:

Mods that replace or rename Haldor's prefab
Mods that patch StoreGui.Show and swallow the call before HaldorOverhaul sees it
Mods that modify Haldor's inventory or dialogue in ways that interfere with the UI hooks

If you experience issues (UI not opening, vanilla UI appearing instead of the custom one, or crashes when visiting Haldor), try disabling other Haldor-related mods one at a time to identify the conflict.

📦 Installation

Install BepInEx, then download the latest release and extract it to BepInEx/plugins/HaldorOverhaul/. Move the two config files (HaldorOverhaul.haldor.buy.json and HaldorOverhaul.haldor.sell.json) to BepInEx/config/, then launch Valheim.

⚙️ Configuration

Two JSON files control what Haldor buys and sells. buy.json lists items he sells to you; sell.json lists items you can sell to him. Each entry looks like this:

{
  "item_prefab": "SwordIron",
  "item_quantity": 1,
  "item_price": 4234,
  "must_defeated_boss": "defeated_gdking"
}

Leave must_defeated_boss empty to make an item always available. Run generate.py to regenerate both files from scratch using the built-in pricing system.

This is my first Valheim mod! I really hope people enjoy it.
