Sources

Release context

Official Valheim news and default-branch patch notes determine which version is public. Public Test announcements are monitored but remain separate. A preview build can be unstable and may change before release, so its values do not enter current calculations merely because they are visible.

Gameplay values

Maintained reference pages are used for crafting costs, food effects, comfort groups, biome progression, and boss context. Every visible database row links to its supporting source and shows the version and review date used by the site. Tool output is derived from those eligible typed records.

Community and competitor research

Steam, Reddit, videos, search results, and competing guides can identify common questions, confusing mechanics, or gaps in the field manual. They are not copied into articles and are not treated as authoritative numerical sources by default. Useful claims are traced to stronger evidence or clearly framed as strategy rather than fact.

Source changes

External pages can move, update, or disappear. Automated and weekly reviews check source freshness and public patches, while correction reports provide another signal. When a source breaks, the record remains reviewable through its version and date but should receive a replacement source before the next material update.

What is excluded

Modded values, private server changes, leaked material, unsourced spreadsheets, generated claims, and future-release speculation stay outside the public dataset. They may be mentioned only with explicit context that prevents visitors from confusing them with the default game.
