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"

---
