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.
