About ValheimBossTrader

From Thunderstore

Unlock 964 items at Haldor based on boss progression. Kill a boss, unlock the next biome's resources. Prices from TraderOverhaul. Fully configurable.

ValheimBossTrader

Unlock 964 items at Haldor based on your boss progression.

Every item sold by the trader is gated behind the boss of its corresponding biome. Kill a boss, unlock the next biome's resources — materials, food, weapons, armor, ammo, consumables, and more. Prices and quantities are sourced directly from TraderOverhaul and fully configurable.


Features

  • Boss-gated progression — Items unlock as you defeat bosses, following Valheim's natural biome progression
  • 964 items across all biomes, organized into 7 categories
  • Real-time unlock — Kill a boss mid-session and items appear immediately, no reload needed
  • Bank system — Deposit and withdraw coins at Haldor. Balance is saved per character and automatically used when buying items
  • Category filter — A panel next to the merchant lets you filter items by category (Materials, Food, Weapons, Armor, Ammo, Consumables, Misc)
  • Choose your traders — Configure which merchants sell items (Haldor, Hildir, Bog Witch)
  • Fully configurable — Adjust prices, stack sizes, toggle categories and merchants via the .cfg file
  • Compatible with r2modman and DatHost — Config is a standard BepInEx .cfg file
  • No hard dependencies — Works standalone, no other mods required

Server-side Usage

This mod must be installed on the server for boss-gating to work correctly in multiplayer, since global keys are stored server-side. Clients do not need to install it (the items will appear for all players when they open the shop).


Bank System

When you open Haldor's shop, a COFFRE D'HALDOR panel appears on the right side of the screen.

  • Deposit — Transfer coins from your inventory to the bank
  • Withdraw — Transfer coins from the bank to your inventory
  • Withdraw All — Empty the bank in one click
  • Bank balance is saved per character in BepInEx/config/BossTrader_Bank/<CharacterName>.dat
  • When buying from Haldor, if your inventory lacks funds, the bank is tapped automatically to cover the difference

Category Filter

A CATÉGORIES panel appears to the right of the merchant list.

  • Click a category to show only matching items
  • Click the active category again (or Tout) to clear the filter
  • The filter resets when you close the shop

Compatibility

  • BepInExPack_Valheim 5.4.2200+ required
  • Compatible with Epic Loot — base item variants only, no rarity conflicts
  • Compatible with Plant Everything, Valheim Plus, and most utility mods
  • Not compatible with mods that fully replace the Trader UI (such as TraderOverhaul itself)
