About this mod Author’s original text
Haldor Trading Overhaul
Transform Haldor into a full-service merchant with buy/sell support, progression-based item unlocks, and an integrated bank tab.
Buy
Sell
Bank
Features
Buy 590+ items from Haldor with category grouping and search
Sell items back to Haldor with balanced sell pricing
Progression-gated unlocks based on defeated bosses
Full controller support for tabs, lists, and actions
Compatible bank workflow: purchases draw from bank and selling deposits into bank
Bank
Haldor can be used as a personal banker:
Deposit moves coins from inventory into your bank balance
Withdraw moves coins from bank back to inventory
Buy and sell operations use the bank flow automatically
Bank balance is synced with HildirOverhaul when both mods are installed
Compatible Mods
Bows Before Hoes is supported. Bows, quivers, and arrows from that mod are integrated into the Haldor shop and follow the same progression model.
Compatibility Notes
This mod targets Haldor only by prefab name.
Other traders (Hildir and modded trader NPCs) continue using vanilla StoreGui
Mods that replace or heavily patch Haldor may conflict
Mods that intercept StoreGui.Show before this mod may block the custom UI
If you see issues around trader UI opening, disable other Haldor-focused mods one by one to identify conflicts.
Requirements
Valheim
BepInEx 5.4.2200 or newer
Advanced Script
generate.py is an advanced config generation script included in this release.
Extracts item and recipe data from Valheim/Jotunn item sources
Builds from prefab data while applying aggressive exclusion rules for junk entries (attacks, spawners, VFX/SFX, creatures, debug rows, and other non-item prefabs)
Uses whitelist and validation logic to keep output focused on real tradeable items
Balances price through multiple layers: biome progression, category multipliers, rarity overrides, recipe ingredient cost analysis, crafting markup, and sell multipliers
Includes price sanity checks to flag suspiciously cheap or expensive results
Run it manually with Python if you want to regenerate buy/sell configs:
python generate.py
Optional custom output directory:
python generate.py "C:/Path/To/BepInEx/config"

Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
Install these first, or the mod will not work:
