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
• 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).

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)

Item Data Source

All item definitions, prices, and stack sizes are sourced from TraderOverhaul by JoeCorrell. Only the base (non-rarity) version of each item is used for vanilla compatibility.

Changelog

1.0.6

• Fix: bankset console command now works correctly (rewritten to intercept Terminal.TryRunCommand directly, bypassing NuGet stub/game version incompatibility).
• Fix: Removed verbose bank logs on each purchase (no more freeze caused by log spam).
• Fix: Missing prefab warnings downgraded to debug level (no longer visible in default BepInEx log output).

1.0.5

• New: Console command bankset <montant> — sets the bank balance directly (requires devcommands). Useful for testing.

1.0.4

• Fix: Bank and category filter UI backgrounds disappearing after a few seconds — textures were being garbage collected by Unity. All textures are now stored as MonoBehaviour fields to prevent collection.

1.0.3

• New: Bank system — deposit and withdraw coins at Haldor. Balance saved per character in BepInEx/config/BossTrader_Bank/. Bank funds are automatically used when buying items (inventory is topped up transparently before each purchase).
• New: Category filter panel — IMGUI panel displayed next to the merchant, with buttons for each category (Matériaux, Nourriture, Armes, Armures, Munitions, Consommables, Divers). Clicking a category filters the item list instantly; clicking again returns to "Tout".
• New: Haldor dark-wood UI theme — Bank and category filter panels use a custom dark wood / amber palette matching Haldor's Black Forest aesthetic.
• Fix: Capes (CapeDeerHide, CapeTrollHide, CapeWolf, CapeFeather, CapeLinen, CapeLox, CapeAsh, CapeAsksvin) were incorrectly categorized as Food; corrected to Armor.

1.0.2

• Fix: load after ValheimLegends to prevent Warp spell conflict (SoftDependency)

1.0.1

• Fix: the mod was silently failing to load on BepInEx 5.4.23.x due to a transitive dependency on MonoMod.Backports introduced by HarmonyX 2.16.0. Pinned HarmonyX to 2.10.1 to resolve this.
• Fix: replaced record type with a plain class to avoid potential runtime issues on .NET Framework 4.8.1.
• Fix: added a guard to skip items with ItemType.None for compatibility with Epic Loot's gamble system.

1.0.0

• Initial release
• 964 items from all biomes, gated by boss progression
• Real-time unlock on boss kill (no reload needed)
• Configurable price multiplier, stack multiplier, and category toggles
• Prices and quantities sourced from TraderOverhaul
