EquivalentExchange

EquivalentExchange is a total gameplay overhaul for Valheim inspired by Minecraft's Equivalent Exchange. Every item has an EMC value, and EMC becomes the universal currency: you craft, build, repair and travel by paying EMC instead of gathering and spending resources.

Compatibility warning

This is not a small add-on. The mod rewrites the core economy — crafting costs, building costs, repairs, food upkeep, loot and portal travel. It is likely incompatible with other global overhaul mods that also change crafting, loot tables or progression, and combining them can cause broken prices, duplicated rewards or blocked recipes. Test on a backup world and use a clean mod profile, ideally with only cosmetic, UI or small quality-of-life mods.

What changes

• Universal currency — item values are calculated from vanilla recipes and trade values; coins and valuables convert at their in-game price.
• Crafting with EMC — the craft button is split in two: the vanilla one spends resources, the second one ("x1 (N EMC)") spends EMC and keeps the materials. Ingredients are still required — EMC pays for the craft, it does not replace materials.
• Building with EMC — construction pieces are paid for with EMC instead of resources.
• Repair with EMC — +1 durability for 1 EMC, applied automatically once per minute to the repair block and equipped gear.
• Transmutation cell — three tabs under your inventory (Feed, Repair, EMC Extraction) slide out as 2×2 drawers with vanilla drag & drop, stack split and Ctrl-click quick move. Opening a tab closes an open chest, opening a chest retracts the drawers, and the chest panel sits below the tabs.
• EMC on slots — while a block panel is open, items in your inventory, hotbar and the block grids show their remaining EMC value on the slot.
• Food upkeep — the Feeding block consumes one food item per minute for 1 EMC, keeping vanilla food buffs running.
• Portal travel — cost scales with distance and carried weight.
• Mob loot — biome- and star-based chances for gear drops with partial durability. Any gear lying on the ground is marked with a semi-transparent, slowly rotating light beam (Epic Loot style) in the neon color of the item's own biome tier — a bronze sword glows BlackForest emerald even in Meadows.
• Character-bound balance — EMC is stored on your character and shown in the inventory, HUD and console.
• Localization — all player-facing texts follow the game language (English and Russian are bundled); switching the game language updates them on the fly.
