Odin's Missing Patch

Warning: this mod is developed heavily with the use of AI, and many of its ideas and even source code is copied from other mods.

Every tweak is actively played and tested in co-op, not only in single player.

The patch Odin forgot: my personal take on the quality of life changes Valheim should have shipped years ago, in one mod. Nothing needs a server install.

Changes beyond QoL

Some tweaks go beyond QoL and change how the game plays, and I ship them on by default because I want them, not because I can argue they are neutral:

Combat stamina is the big one. Eliminating stamina usage outside of combat removes a huge part of Valheim's exploration. This drastically simplifies climbing mountains and allows for swimming in the ocean.
Keep gear on death removes the stakes of dying on a world already set to the Casual death penalty. The corpse run is a real punishment, but not one I have the time for.
Endless fuel deletes the coal-and-wood upkeep of a lit base. Small, but it is an economy.
Pocket upgrades hands you Haldor's first extra inventory row two bosses early. It is a progression change, not a QoL one: the cramped backpack of the Swamp and the Mountains is meant to be part of the game, and I would rather spend those hours on the game's other ideas.

What it does

Station range — scales a crafting station's build/craft/repair radius, and how far an extension may stand from it, by a multiplier (2 by default).
Comfort range — widens the radius Rested counts furniture in, by the same kind of multiplier.
Endless fuel — tops the fuel back up on every campfire, hearth, torch, brazier and hot tub, so nothing that burns for light goes out.
Mist clear range — scales a demister's push radius (wisplight, wisp torch, anything else), doubled by default.
Combat stamina — drops the stamina cost of sprinting, jumping, swimming, sneaking, building, chopping, mining and swinging while nothing hostile is within 25m and nothing that has noticed you is coming for you. A boss fight always costs stamina: every cost is back while a boss health bar is on screen. Free swimming means no drowning unless attacked, since drowning starts at empty stamina.
Instant comfort — sitting down grants Rested immediately, instead of after the game's ten seconds of Resting.
Fireside healing — folds comfort level × 2 health into the game's own ten-second food regen tick while you are Resting.
Fast portals — ends the trip as soon as the screen is fully black and the far side has loaded, instead of the game's flat eight seconds. Dungeon and cave entrances are instant, with no black screen at all.
Keep gear on death — makes casual death penalty even weaker: an item-type list (weapons, armour, ammo, tools, utility, trinkets, consumables by default) defines which stay in your inventory and stay equipped.
Area repair — after a hammer swing lands, repeats the game's own repair on every damaged piece within 10m, closest first. Hold Left Alt for the single piece.
Nearby crafting — while a craft, upgrade or build is being checked or paid for, the game also checks player-placed chests within 20m. Your backpack pays first, the nearest chest pays the rest.
Quick stack — one key (.) pushes every carried stack into the nearest chest in range that already holds that item, merging into its stacks before taking a slot. Each chest that took something glows with a count. Equipped items, the hotbar (a switch) and favourites stay. Alt-click an item to make it a favourite.
Chest favourites — Alt-click an item inside an open chest to mark the chest for that kind of item. Quick stack and Fill the chest's stacks put it there even when the chest holds none.
Nearby fuel — lets the four manual add-fuel interactions (fire, smelter, oven, shield generator) draw their one unit from a chest when your backpack has none.
Add all — Shift + Use on a fire, smelter, kiln, oven, cooking station, shield generator or ballista to fill up fuel, ore, food and bolts. Uses backpack first and the chests after.
Auto repair — on Use of a crafting station repairs all repairable items.
Chest buttons — replaces Take all and Stack all with five icon buttons placed beside the panels rather than on them: fill your stacks from the chest, and, down the chest's side, take all, place all, fill the chest's stacks and sort the chest.
Inventory buttons — stack nearby and sort, beside your inventory. The sort merges stacks and orders by kind, then name, then quality, below the hotbar. What you have equipped and your favourites stay in the slot you put them in, and everything else is laid out around them.
Power picker — adds a Forsaken powers ring to the radial menu, so you can pick a power without running to the sacrifice stone.
Equip while running — a hotbar press while sprinting still equips the weapon, shield or armour.
Auto shield — drawing a one handed weapon raises a shield with it. It picks the shield you marked as a favourite first.
Pocket upgrades — Haldor sells the two extra inventory rows, Wider Pockets and Deeper Pockets, once the boss you choose has fallen in that world. Wider Pockets waits for the Elder instead of Moder by default; Deeper Pockets keeps the Queen.
Shared map table — come within 64m of a cartography table and your map is written onto it and its map onto yours, silently, with no click. It is read again whenever someone else has written to it, and written again when a pin of yours changes nearby — only when the table is actually missing something of yours, and never more than every thirty seconds.
Auto pins — dungeon and cave entrances, ore deposits you strike (not tin, which is everywhere; soft tissue from the Mistlands giants counts) and places (fuling villages and other ruined settlements, tar pits, dragon eggs, Dvergr excavations and watchtowers, ...) get an ordinary map pin when you come within 40m. Every pin you get appears on the map of every other player online at that moment, and when you join, their pins appear on yours.
Pin looks — those pins are coloured by their biome, dungeons and dragon nests get icons of their own (crypt, frost cave, dragon nest, any other entrance) that name the place when you hover them, and ore and place pins hide when the large map is zoomed far out. Toggles at the bottom right of the large map, beside "Visible to other players", show or hide dungeon, ore and place pins.
Death pins — a death pin goes away by itself once your grave is gone, whoever emptied it, and a death that leaves no grave leaves no pin.
Player marks — a small glowing mark over every other player who is behind a hill or a wall, or more than 50m away, and on the screen's edge in their direction when they are off screen.

Configuration

BepInEx/config/rauschekuh.odinsmissingpatch.cfg, written on first run. Every tweak has an Enabled switch; the ranges have a multiplier (1 is vanilla), and the rest have the settings named above. Changes apply while the game runs, including from an in-game config manager.

Translations (AI generated)

The mod's buttons, hover text and messages follow the language Valheim is set to. English, German, Russian, Chinese, Spanish, French, Brazilian Portuguese, Polish, Italian, Japanese and Ukrainian ship with it, each built on Valheim's own wording. Any other language is a column in translations.csv, which sits next to the DLL in BepInEx/plugins/rauschekuh-OdinsMissingPatch/. Open it in a spreadsheet or a text editor, add a column headed with the language exactly as Valheim names it (Dutch, Czech, Portuguese_European, ...) and fill in the rows — anything left empty stays English, and $1 and $2 are the numbers and item names the game fills in, which may stand anywhere in the sentence. Send one over and it ships with the next version.

Multiplayer

Client side; no server install, and nothing required of anyone else.

Most of it never leaves your machine. Four things touch the world, and each does it the way you would by hand: area repair sends the game's own repair, one piece at a time. The chest tweaks take a chest over for the write exactly as opening it does, skip a chest someone else has open or that you could not open yourself, and respect the per-chest Nearby use switch stored with it. Endless fuel writes the fuel on fires your machine owns — Valheim gives a fire to whoever is nearest, so a fire only a modless player stands by burns down as usual. The shared map table writes a table exactly as its Write button does, and never one behind a ward you cannot use.

Auto pins go straight to every player with the mod who is online, and a player who joins gets everyone's once (Share, on by default; off, they wait for a table). Each player takes them under their own settings, so a category you switched off never shows up. They travel on map tables in the game's own format too, so a player without the mod reads them from a table as ordinary shared pins. Removing one is yours alone: other players with the mod keep theirs and bring it back to the table.

Two caveats. Client-side range tweaks reach only you: a player without the mod has vanilla range at the same bench and sees mist close in at the vanilla distance. And keep gear on death goes further than the Casual death penalty a host chose, for you — on a world set any harsher it switches itself off, so it can never undo the penalty a host asked for.

Install

A mod manager (Gale or r2modman), or drop the zip's contents into BepInEx/plugins/rauschekuh-OdinsMissingPatch/. Requires the BepInEx pack for Valheim.

Credits

Several tweaks cover ground others got to first, and are worth a look if you want that one thing on its own or want it server-enforced. Do not run both of a pair.

Endless fuel follows Digitalroot's Eternal Fire, which also covers ovens and smelters and is configurable per fire type.
Mist clear range and fast portals do what Crystal Ferrai's Clear The Air and Proper Portals do; both default to vanilla and can be enforced by a server.
Combat stamina is modelled on Cartur's Safe Stamina; this one also counts an enemy that has noticed you, wherever it is.
Area repair does what Venture Area Repair does at a fixed 20m; here the radius and the single-repair key are settings. Azumatt's AzuAreaRepair covers the same ground.
The chest tweaks and auto repair cover part of Zellds' SmartCraft-Storage, which goes much further — stations that feed themselves, restocking, animal feeding. This one keeps every move yours.
Equip while running is what blacks7ar's EquipGearWhileRunning got to first, and that one is a drop-in with nothing to configure; here it is a switch beside the rest.
Auto shield follows Vapok's ShieldMeBruh.
Pocket upgrades follows chooweey's EarlyHaldorPockets.
Auto pins do what Searica's Discovery Pins does, which also clears the death pin when you pick your grave back up and mass-pins on a key; here the pins are shared through map tables instead.
Shared map tables go where nbusseneau's Better Cartography Table goes by another road: that one adds public and private pins and syncs on use; this one keeps the game's own table and syncs by walking up to it.

Recommendations

Mods I run beside this one. None of them overlap it — they fill the gaps this one leaves.

Unshamed — gives you back the achievements Valheim switches off the moment it sees a mod. It unlocks nothing you have not earned, and it can backfill the progress your modded hours already made.
HUD Compass — a compass across the top of the screen, carrying live markers for your ships, carts and portals so you can find where you left them.
Target Portal — pick the portal you are travelling to off a map instead of juggling tag pairs, with per-portal access rules and favourites. This one wants to be on the server too.
Plant Everything — berry bushes, mushrooms, flowers and every kind of tree on the cultivator, with growth timers on the plants and a setting for each one.
