Valheim Deep North Materials Checklist: Frostcore & More

The Deep North update for Valheim added more than thirty named crafting materials, and this checklist groups the named materials — Frostcore, Bloodgold, Moose Hide, Timberwood and the rest — by category, alongside the two new production stations and three station extensions the patch notes name. Valheim 1.0 launched on 9 September 2026 from developer Iron Gate and publisher Coffee Stain Publishing, and this checklist separates the official content list from recipe details documented in an in-game press guide.

The Deep North materials are the new crafting-item category Iron Gate added with Valheim 1.0, covering everything from frozen ores to animal parts to purchasable seasonings. The official patch notes list Bloodgold, Crown Jewel, Dead Pulp, Elaking Hair Bundle, Embers, Frostcore, Frostfire Essence, Frozen Branch, Hook, Ice, Leather Straps, Liquid Frost, Long Claws, Moose Hide, Moose Meat, Moose Sinew, Molds & Casts, Nornathread, Petrified Tissue, Seal Blubber, Seal Pelt, a purchaseable Seasoning of the Gourd, Thunderblood Essence, Timberwood and Writhan Roots under the Crafting section, alongside eleven new creature trophies including Barka, Elaking, Eyeless One, Frost Blob, Hexen, Krigen, Lava Blob, Moose, Pulp, Seal and Writhan Trophies. Players care about this list because it’s effectively the recipe backbone for the entire new biome — every Nord, Frostfire and Thunderblood weapon in the update draws on some combination of these materials, even though the patch notes themselves don’t spell out which recipe uses what.

For the wider rundown of everything the update shipped — weapons, armour sets, dungeons — the Deep North update overview covers the full patch beyond just materials.

Some sources are stated plainly in the patch notes and some are not. The four new plantables — Kale, Oats, Poteitr and Timberwood — are grown rather than looted, and Timberwood is plantable, which lets you farm the tier’s building material instead of hauling it, and it feeds the new Scalewood structures, according to third-party reporting on the update. The eleven trophies line up with named new enemies — Barka, Elaking, Eyeless One, Hexen, Krigen, Moose, Seal, Writhan and the various Pulp variants all appear in the same patch notes’ creature list, which strongly implies each trophy drops from its namesake creature, though the notes never state that link directly. Two trophies break that pattern: Frost Blob and Lava Blob are listed as materials with no matching enemy entry in the same notes, so their actual source is unstated. Bloodgold is the trickiest of the bunch — the patch notes confirm what it’s for but not where it comes from. The official notes are clear about what Bloodgold is for — four Bloodgold ammunition types (Arrow, Bolt, Missile, Payload) and a dedicated storage stack — but just as clear by omission about what they don’t cover: no mining location, no refining process, no confirmed smelting station, and no numeric stats. PC Gamer’s illustrated in-game walkthrough provides that missing chain: defeat a Gammeltroll, break its petrified remains with ember charges, then smelt the Petrified Tissue into Bloodgold in a Blast Furnace. This is reported gameplay evidence, not a recipe printed in the official patch notes.

The patch notes don’t publish drop rates or recipe costs; the two station recipes are documented from the live game by PC Gamer (Frigid Kiln 10 Frostcore, 20 Stone, 5 Ice — unlocked by picking up Ice; Frost Foundry 10 Frostcore, 15 Iron, 20 Stone — unlocked by touching a Frostcore), so “best method” here means matching effort to those two builds and to what the notes confirm exists.

On the time cost: the patch notes don’t give a recipe list, so there’s no way to state a total hour count for a “finished Nord loadout” honestly — what’s known is that the checklist itself spans 30+ materials, 11 trophies and four plantables before any station is even built, so choose a specific crafting target before gathering everything — the Valheim 1.0 overview covers the rest of the update.

The payoff for gathering these materials is access to the two new production stations and three station extensions, plus the weapon and ammunition lines tied to Bloodgold, Frostfire Essence and Thunderblood Essence by name.

Frostfire and Thunderblood essences

Deep North progression introduces a completely new collection of metals, creature drops, essences, plants, crafting components, and production stations, and the patch notes list a full Frostfire weapon line (Sword through Crossbow) and an identical Thunderblood line next to their matching essence materials. The naming pattern is obvious, but the notes never state that Frostfire Essence is literally the crafting cost for a Frostfire Sword — that’s an inference from shared names, not a confirmed recipe.

Bloodgold ammunition

The patch notes list Bloodgold Arrow, Bloodgold Bolt, Bloodgold Missile and Bloodgold Payload as new ammunition types, plus a separate Bloodgold Stack for storage. None of the four ammo types have a stated crafting cost in the notes, so verify quantities against the current in-game recipe. A tested recipe from gameplay is a different source from an estimate; absence from patch notes does not make it false.

Frostcore and recipe unlocks

The recipe unlock described above is documented by PC Gamer with in-game screenshots. It should be attributed to that walkthrough, not presented as a quote from the patch notes or dismissed as a naming-based guess.

Bloodgold refining is not the same as making a Cast

For the Intricate Key, the documented sequence is: Blast Furnace for Bloodgold; Black Forge for the Cast; Frost Foundry to finish the key using Liquid Frost from the Frigid Kiln. A Mould is not put directly into the Frost Foundry.

“Every trophy matches a named enemy in the patch notes”

Mostly true, but not entirely. Nine of the eleven trophies — Barka, Elaking, Eyeless One, Hexen, Krigen, Moose, Pulp, Seal and Writhan — line up with creatures named elsewhere in the same notes. Frost Blob and Lava Blob don’t have a matching creature entry in the Creatures section, so assuming they drop from an obvious source is a guess, not a confirmed fact.

Two hotfixes landed two days after launch and both touch things that matter for a materials run. Punching snow no longer removes it, while landing on a snowy area without directly walking over it now causes the snow to disappear, which changes how you clear space before placing Timberwood or Scalewood structures. Separately, players had discovered a couple of days earlier that the new Timberwood drawbridges were too narrow to fit a cart across, and the fix for that shipped in this same patch. Greydwarf Shamans in the Deep North were also dealing and healing too much, and that’s now fixed. On the platform split: 1.0.10 is listed for all platforms, while 1.0.12 is listed as Steam-only, with its fixes planned for other platforms through an upcoming hotfix whose release date has not been communicated. This describes the platform split in the 11 September notice, not a live inventory of every console build; check your platform’s latest patch before assuming a fix is absent. Anyone running mods or a long-lived world should back up character and world saves before updating, given both the scale of new content and the item-stand bug above — and if you’ve used dev commands anywhere near your build, the devcommand cheat-flag guide covers how that flag interacts with achievements.
