Earlier hotfixes and recovery limits
Official September 11 notice checked 2026-09-19; September 18 patch notice checked 2026-09-20. This publication review does not revalidate extracted recipes or certify installed patches.
| Platform | Published status | Next check |
|---|---|---|
| Nintendo Switch 2 | The delayed patch has arrived; crossplay is restored according to Iron Gate. | Finish available updates and test the current join code. |
| Steam, Xbox and other supported platforms | Iron Gate says crossplay continues during the staggered 1.0.17 rollout. | Record client and server versions; platform version numbers may differ. |
| A Steam client or server left on an older branch | The earlier Switch 2 delay no longer justifies the temporary downgrade. | Back up first, check the selected branch and follow current publisher instructions. |
The earlier Steam default_old workaround is historical. Iron Gate’s updated notice says the delayed Switch 2 patch has arrived and crossplay is restored; its October 6 notice says crossplay continues during the 1.0.17 rollout. The older Steam capture retains its original 2026-09-12 review date.
Iron Gate’s September 18 update says item-stand levels and variants were lost during conversion to the 1.0 save format. Patch 1.0.12 protects later conversions; it does not restore already-lost data. Back up the current world and characters before recovery. The publisher describes restoring a pre-conversion world backup or retrieving affected items from a copy of it. Restoring the earlier world discards subsequent world progress. Consult the linked recovery instructions before changing saves; no recovery procedure was tested here.
Deep North heavy armour can now be repaired on the applicable hotfix. Steam 1.0.12 corrects unintended Forge of Potential unlocks and adds an achievement opt-in after earlier devcommand or mod use.

What the review labels mean
| Label | What it establishes |
|---|---|
| Official release context | A change or feature announced by Iron Gate. Exact gameplay values need their own evidence. |
| Build-specific serialized data | Named values and object relationships read from identified game files. This does not demonstrate runtime behavior or a completed gameplay route. |
| Scoped managed-code check | Selected crafting and smelting method instructions were inspected in named assemblies. This supports only the described rules, not a played route or every modifier. |
| 1.0 researched walkthrough | Current published walkthroughs and databases support the route. Disagreements and not yet tested details are called out in the guide. |
| Pre-1.0 reference | Older mechanics or recipes remain available with their source dates. They have not been fully revalidated against 1.0. |
| Nominal item stats | Published base values and quality increments. These do not calculate character skills, target defenses or every game modifier. |
A check date records when a source was reviewed. It is not a claim that the wiki team played through that encounter or tested every platform. No firsthand 1.0 gameplay test is claimed.
Supply targets, suggested routes and preparation checklists are editorial advice. World modifiers, multiplayer group size and procedural terrain can change what your expedition needs.
First bronze: pinned 1.0.15 server evidence
On 22 September 2026, an isolated SteamCMD installation of the public Valheim dedicated server yielded build 25390671, reporting game version 1.0.15. The existing Steam client and player saves were left in place. Iron Gate’s 1.0.15 notice was the latest public notice checked that day.
All 11 scoped bronze recipe, construction and conversion records matched the earlier reviewed 1.0.12 snapshot. All 59 referenced serialized proof objects were byte-identical, despite changes to the overall bundles. The forge station still stores m_upgrader = 0. Static inspection found the same resolved instruction flow in ten selected crafting and smelting methods, including requirement checks, resource consumption and processed-output spawning.
What this supports: a base bronze axe costs 4 Wood, 8 Bronze and 2 Leather scraps; bronze needs 2 Copper and 1 Tin; a new forge adds 6 Copper, 4 Stone, 4 Coal and 10 Wood. A new kiln and smelter each add 20 Stone and 5 Surtling cores. Copper and tin each use one ore and a nominal two Coal per bar. The upgrade-only resource entries do not count in ordinary crafting at the forge.
Boundary: this is a server-asset and managed-code check, not a played client route. Crafting skill can grant bonus bronze output, so the planner’s one-bronze-per-craft figure is a conservative baseline. Unlock conditions, timing, world modifiers, multiplayer behavior and other platforms were not tested. The broader Bronze Age recipe catalog outside the four selectable planner items retains separate evidence limits. Existing version-2 saved plans will show an evidence-source change with no material-quantity change; version-1 plans remain unknown. Neither case rewrites an existing save.
- Valheim 1.0.15 dedicated server build 25390671: first-bronze extraction
Base construction and crafting inputs, bronze alloy and first-bronze equipment costs, ordinary wood-to-coal and copper/tin conversions, and the scoped upgrade-resource and smelter rules documented in the evidence review.
Local game-data extraction · Checked . Isolated public-branch server installation. Eleven scoped serialized records and 59 referenced proof objects match the earlier reviewed snapshot byte for byte. Selected crafting and smelting instruction flows were checked statically; no player-world gameplay test or platform-wide claim is implied.
Bronze reference check: installed build 25253764
On 19 September 2026, a read-only inspection of the existing Steam installation checked 11 bounded recipe, construction and processing records. The stored alloy inputs, station materials and ordinary equipment amounts agree with this planner’s historical reference. The installation was not updated or launched, and this is not a claim about the newest public build.
At this earlier review, the extra resources marked for upgrades had no established inclusion rule. The later 1.0.15 static rule check above resolves their treatment for ordinary forge crafting within the selected methods.
The smelter references identify copper and tin inputs and outputs and store a fuel-per-product parameter of two. The later 1.0.15 check above establishes the nominal conversion behavior within selected methods. Timing, modifiers and played outcomes remain separate.
Extraction scope and fingerprints
The new build-specific profile reuses the existing file parser with separate source, object, type and field canaries. It preserves 208 selected fields and 405 unique evidence byte ranges, checked with an independent primitive-byte decoder. Earlier build profiles remain unchanged. Unity version: 6000.0.75f1.

Direct vanilla evidence: build 25185596
On 10 September 2026, the already-owned Steam installation was updated from build 21981559 to 25185596. A read-only, field-allowlisted exporter parsed the vanilla Unity serialized files without launching, injecting into or modifying the game. Ten normalized records retain the manifest, source bundle, serialized member, object, type, field, byte range and SHA-256 evidence for each value.
A Codex research task prepared this extraction. A separate Codex agent independently reproduced the snapshot and checked the retained byte ranges, values and relationships. The review corrected the station prerequisites before publication.
| Record | Verified serialized defaults | Boundary |
|---|---|---|
| Eternal Pyre | 10 Stone + 1 Fader Relic at a stonecutter; its WispSpawner points to LuredFaderEmber. | Verifies the Fader reward → structure → ember-prefab relationship, not a measured spawn rate. |
| Frigid Kiln | 20 Stone + 10 Frostcore + 5 Ice, with a Workbench nearby; Ice is its fuel and its output points to the internal Liquid Frost prefab. The stored fuel-per-product value is 5. | Stored parameters, not a timed gameplay batch. |
| Frost Foundry | 15 Iron + 20 Stone + 10 Frostcore, with a Workbench nearby; its key conversion maps Cast: Intricate Key + Liquid Frost fuel to Intricate Key. | The selected conversion is one of 30 stored station conversions; runtime queue behavior was not observed. |
| Cast: Intricate Key | Black Forge level-4 recipe: 5 Bloodgold + 1 Mould: Intricate Key → one cast. | The stored recover flags do not prove mould refunds or retry behavior. |
| Mörkhalla gates | Two distinct door prefabs require Intricate Key. One stores consume-key and cannot-close as true; the other stores both as false. | The asset records do not identify which player-visible gate checkpoint each prefab occupies, so exact checkpoint consumption remains unresolved. |
| Kall altar | The offering bowl stores 3 Malicious Blood and points to Kall Fimbulbringer. | Does not establish partial offerings, failed-attempt refunds or summon persistence. |

Still unresolved: which of the two serialized Mörkhalla gates is the chained player checkpoint; Mörkhalla and invasion persistence; partial offerings, retries and refunds; Forge of Potential loss behavior and odds; and the post-Kall interaction. The complete Winding Tunnels → Mörkhalla → invasion route order remains corroborated research guidance because serialized object relationships do not by themselves prove the player’s traversal sequence.
Changes that affect older guides
The following corrections are based on the detailed release notes. A corrected paragraph does not certify every older value on the page.
Mistlands visibility
Wisplight, Wisp torch and Mistwalker clear farther; all Mistlands weapons now clear mist. Keep a spare light and a marked recovery route. Check visibility with your actual equipment before crossing a drop.
Still to check: Exact clearing radii and equipment interactions are not established by the notes.
Late-game gear durability
Mistlands and Ashlands gear received higher durability. Check your item’s current durability and repair before departing. Keep the reserve kit in the guide.
Still to check: New durability values and per-item coverage are unresolved; this does not revalidate crafting costs or station levels.
Ashlands encounters
Spawn chances were reduced for multiple Ashlands enemies, while the interval between Charred spawns was shortened. Do not read the rebalance as a guaranteed longer quiet interval or lower overall difficulty. Keep a short route back to cover.
Still to check: Spawn probabilities, intervals and resulting difficulty are not quantified.
Black Forest Bear hunts
Black Forest Bjorn spawn chance and health were reduced. Use a prepared search circuit; do not rely on an old health figure or a guaranteed encounter.
Still to check: The notes do not supply new health values, spawn chances or changes to Vile behavior.
Base pieces and raids
The set of build pieces tagged as player base changed in 1.0, and patch 1.0.14 strengthened the PlayerBase effect on some pieces so they block enemies more. Treat old piece lists and raid-eligibility advice as pending review. Preserve an exit, spare kit and protected livestock.
Still to check: Which pieces changed, suppression coverage and applicability to the new events remain unconfirmed.
Haldor and carrying space
Haldor offers inventory upgrades; Deeper Pockets and Wider Pockets are named in the release. Inspect the current shop and distinguish inventory slots from carrying weight before spending coins.
Still to check: Prices, slot gains, prerequisites and interaction with carrying equipment remain unresolved.
Trinket coverage
1.0 adds Neckstabber and Witch Crown. Use the thirteen-entry table for its pre-1.0 scope; it is not the full released trinket collection.
Still to check: New trinket effects, acquisition and recipes are not established here.
