Viking Codex

1.0.9 — Native data reference update

• Add 4,332 deduplicated native prefab relationships from an isolated vanilla 1.0.20 capture. Show recorded placement/cultivation biomes separately from curated progression groups.
• Read item descriptions and base quality-one tooltips from the running game. Show each upgrade's actual ingredient costs, station and station level, and distinguish alternative ingredients from cumulative costs.
• Show native creature base health, boss status and already-known drops; explain that encounter settings, stars and mods can alter them.
• Keep unknown relationship endpoints and drop names hidden. Preserve protocol 2 and the existing session discovery-sharing policy; this update does not import a joining character's old progression.
• Dedicated vanilla validation passed 3,236 recipe/creature formatting and spoiler checks. This is bounded data validation, not a claim that all gameplay or multiplayer states were tested.
• Some progression groups and source paths remain unclassified. Captured links are not guaranteed obtainability, exact drop odds for every world, or universal 100% completeness.

Stable full release · JustQOL Viking Series

Discover more. Explore together. Viking Codex brings your discoveries, crafting knowledge and biome checklists into one native Valheim interface. Browse what you know, follow clues toward what you have yet to find, and share supported item discoveries with other Vikings on your server.

Features

Your own Viking encyclopedia

• Browse base-game items, creatures, crafting recipes, building pieces and crafting stations.
• Filter by biome, category and discovery status. Sort by progression or alphabetically.
• Search discovered content and discovery clues without exposing hidden names.
• View an item and its related recipes together without duplicate recipe rows.
• See newly discovered entries marked NEW until you view them during that session.

Clues without spoilers

Undiscovered entries display a clue instead of revealing their identity. A clue might point you toward red fruit growing on low bushes, while the item's name and recipe details stay hidden. Unknown icons appear as silhouettes where an icon is available. Select an entry to read its full clue, or search the clue to narrow your next destination.

Biome discovery checklists

Each biome shows its discovered count, completion percentage and discoveries remaining. Search and category filters do not shrink that biome's completion total. Discovered entries appear first in the All view, and Unclassified entries have a separate filter.

Completion refers to the entries assigned to that biome in the current catalog. It does not represent every possible activity or discovery in Valheim. Unclassified entries remain available in the All view.

Crafting information at a glance

Review descriptions, known ingredients, crafting stations, station levels and related recipes. The Codex distinguishes discovered, recipe known and currently craftable states. Missing resources and station requirements are highlighted; unknown ingredients and undiscovered recipe details stay hidden.

Optional Wiki buttons open mapped pages for discovered entries when you choose to use them. Viking Codex makes no background Wiki requests.

Discover together

Supported base-game collectible-item encounters contribute to the server's shared discovery history, including supported food and equipment. Other connected characters receive that knowledge through Valheim's native item-registration and recipe-unlock logic.

• Sharing applies across the server, rather than only to nearby players.
• An item encounter can contribute even when the collecting character already knows the item.
• Joining or reconnecting characters receive eligible knowledge already recorded by that server, with offline catch-up enabled by default.
• Joining a server does not upload a character's entire previous knowledge. Contributions come from supported encounters during play.
• Learned knowledge belongs to the character; shared history is stored separately for each world.
• Creature encounters and crafting-station knowledge are not shared.

Sharing grants knowledge, not physical items. Resources, crafting stations, station levels and other crafting restrictions still apply.

How to use

| Control | Action | | --- | --- | | Viking Codex main-menu button | Open the controls and discovery guide | | F8 in a world | Open or close the Codex | | Codex inventory button | Open the Codex from your inventory | | Up / Down outside text fields and dropdowns | Move between entries | | Escape or Close | Close the Codex and return to the game |

Choose a biome, category and discovery filter, then select an entry to inspect it. Clear filters resets the view. The main-menu guide is available before entering a world; your character's catalog is browsed in a loaded world.

The interface uses Valheim wood panels, Averia Serif text, warm highlights and native controls to match the JustQOL Viking Series.
