Materials and Metals
A tour of the wood tiers, the metal ladder from bronze to flametal, and the support materials like coal, surtling cores, flax, and barley.
Every tier of gear and building in Valheim is gated behind a material, and most materials are locked to a single biome. Knowing what comes from where is half of planning a run. This page walks the wood tiers, the metal ladder from bronze up to flametal, and the support materials, coal, surtling cores, flax, and barley, that the whole economy quietly depends on. Remember the rule that shapes all of it: you cannot portal metal, so every bar of ore is a boat trip.
Wood tiers
Wood is not one material but a ladder. Plain Wood comes from any tree. Fine Wood comes from Birch and Oak in the Meadows but needs a bronze axe, so it is a reason to return after the Black Forest. Core Wood comes from the pines of the Black Forest and feeds smelters, kilns, portals, and structural support. Ancient Bark comes from Swamp trees, and Yggdrasil Wood from the Mistlands. Each tier unlocks more building and crafting options, so wood gathering never fully stops.
The metal ladder
Metals are the spine of gear progression, and each one belongs to a biome and a smelting method.
| Metal | Biome | Source | Smelted in |
|---|---|---|---|
| Bronze | Black Forest | 2 Copper + 1 Tin per bar | Forge |
| Iron | Swamp | Muddy Scrap Piles in Sunken Crypts | Smelter |
| Silver | Mountains | Deep veins, found with the Wishbone | Smelter |
| Black Metal | Plains | Black Metal Scrap from Fulings | Blast Furnace |
| Flametal | Ashlands | Flametal Ore veins | Blast Furnace / Black Forge |
Two details trip people up. Bronze is an alloy: you combine Copper and Tin at the Forge rather than mining it directly. Black Metal and Flametal need a Blast Furnace, not the basic Smelter, and the Blast Furnace needs the Artisan Table built from Moder’s Dragon Tear. Flametal is the highest current weapon and armor tier.
You cannot carry ores or metal bars through portals. Every metal run is a boat trip home, so smelt at base and plan your Longship hauls around it.
Stone and Mistlands materials
Building stone climbs too. Plain Stone off the ground gives way to Grausten, the Ashlands building stone, with Black Marble from Plains tar in between. The Mistlands runs its own magic and building economy: Black Cores power magic and crafting stations, Soft Tissue from giant petrified bones builds and feeds the Eitr Refinery, Carapace from Seekers makes armor and weapons, Sap fuels the Black Forge, and Eitr is the mana resource behind every spell.
The support materials
Some materials never make a weapon but gate everything that does. Coal is the fuel for smelters and furnaces, made in the Charcoal Kiln or dropped by Surtlings. Surtling Cores come from Black Forest Burial Chambers and the Swamp, and they are required to build Smelters, Charcoal Kilns, and Portals, so they are an early bottleneck worth hoarding. Flax and Barley are Plains-only crops: Flax becomes Linen Thread on the Spinning Wheel and Barley becomes Flour on the Windmill, both feeding the top-tier food and gear. Without these support materials the headline metals never leave the ground.
