Item Upgrader

Client-side item upgrade roulette for Valheim. Version 0.5.1, compiled against supplied Valheim 1.0.16 libraries. The menu supports Russian and English, selected automatically from the game's language setting. Other game languages use the English mod UI; item names keep the game's language.

Features

• Automatic Russian/English interface, including tooltips, search, messages and errors.
• Language changes refresh existing labels and item names without recreating the UI or changing a roll.
• Rewards unlock with the current character's discovered materials and crafting recipes.
• Top-left ALL ITEMS / ВСЕ ПРЕДМЕТЫ switch temporarily enables all obtainable rewards; off on entering a world.
• Test, obsolete and NPC-only item records are excluded, including the old boss hearts and stamina upgrades.
• Choose a stake and a desired reward, including their quantities.
• View the success chance and spin a smooth five-second wheel.
• Rebalanced metal and Deep North values, with equipment limits by category and biome.
• Quality bonuses capped at ×2: a four-quality item uses ×1 / ×1.3333 / ×1.6667 / ×2.
• Fast scrolling, searchable catalog and reusable UI cards.
• Claim large rewards in batches when inventory space is limited.

The mod runs locally. A server installation is not required; odds and outcomes are calculated on the client.

Installation and updating

Install with Thunderstore Mod Manager or r2modman, or copy BepInEx/plugins/ItemUpgrader into the game's BepInEx/plugins folder. BepInEx is required and declared as a dependency.

Close the game before updating. Replace the old DLL and keep only one copy. Preserve your cfg, ItemValues.json and AutomaticValues.json. Untouched automatic prices recalculate; manual prices and zero exclusions remain. The first 0.4.0 rebuild backs up the old price files. The plugin ID is valheim.itemupgrader.

How to play

1. Press F8 to open the menu; Esc closes it.
2. Select an unequipped inventory item and the quantity to spend.
3. Select an unlocked reward and its quantity. Use the top-left ALL ITEMS / ВСЕ ПРЕДМЕТЫ switch to bypass progression if desired.
4. Check the displayed chance and press UPGRADE / УЛУЧШИТЬ.
5. On success, press CLAIM / ЗАБРАТЬ. On failure, the selected stake is consumed.

The selected stake is consumed on every attempt, including successes. Rewards are created at quality 1 with full durability. Closing the menu does not cancel a started attempt. Inventory and pending rewards use normal character saving and logout.

Language

Set the language in Valheim's settings. Russian selects the Russian mod interface; English selects English. Other languages use English interface text. Labels, filters, placeholders, tooltips, win/loss messages, partial claims and errors follow this choice automatically. Native item names and the catalog search continue to use the game's language, and cached names refresh when that language changes. No separate mod language setting is required. Existing selections, progress, prices and pending rewards are preserved.

Progression and catalog

The default catalog follows the character's own saved discoveries, including earlier discoveries from an existing save. A material or non-craftable reward unlocks when the game marks it as known; craftable gear also unlocks when its recipe is discovered. Merely visiting a biome or defeating a boss does not reveal every item from that biome. Processing outputs unlock after discovery of the output, rather than discovery of the input alone.

The ALL ITEMS / ВСЕ ПРЕДМЕТЫ switch is off by default and resets on entering a world or changing character. It bypasses discovery only: debug/obsolete/NPC-only items remain excluded. Turning it off clears a selected reward if that reward is still locked. The switch is disabled during a spin; existing pending rewards remain claimable.

The obtainable catalog is built from enabled crafting recipes, loot, pickups, vendors, production and reachable processing routes in the installed game, with explicit exclusions for known obsolete records. Unsupported DLC items are hidden. The catalog is cached and refreshed after discoveries; discovery does not rebuild item prices.

Configuration and balance

Settings: BepInEx/config/valheim.itemupgrader.cfg. Prices and the generated runtime catalog: BepInEx/config/ItemUpgrader.

Let r = stake value / total reward value. For a more expensive reward, chance = min(MaximumChance, ReturnRate × r^UpgradeChanceExponent); otherwise chance = min(MaximumChance, ReturnRate × r). There is no artificial minimum chance.

Quality increases value by at most ×2, and wear discounts it further. Crafting markup is applied once to the raw acquisition chain; equipment has an exchange factor and category/biome limit. Embedded upgrade idols do not inflate the value of finished gear.

Edit individual prices in ItemValues.json, then click RELOAD VALUES / ОБНОВИТЬ ЦЕНЫ. Zero disables an item; deleting its entry restores automatic calculation. Explicit custom prices override automatic category limits; the quality cap still applies. Preserve AutomaticValues.json when updating.

Русский

В 0.5.1 добавлены русский и английский интерфейсы. Язык выбирается автоматически по настройке игры: русский → русский, английский → английский; для остальных языков интерфейс мода английский. Переведены кнопки, поиск, категории, подсказки, статусы и ошибки. Названия предметов берутся из языка игры и обновляются при его смене.

Нажми F8, выбери ставку и желаемую награду, задай количество и нажми УЛУЧШИТЬ. При успехе награду можно забрать, при проигрыше ставка сгорает. В 0.5.0 каталог открывается по знакомым материалам и рецептам персонажа. Сверху слева есть переключатель ALL ITEMS / ВСЕ ПРЕДМЕТЫ: по умолчанию выключен, включение временно снимает ограничение прогрессии. Служебные, тестовые и устаревшие предметы исключены в обоих режимах. Ранее открытые предметы существующего персонажа учитываются сразу; награды прошлой версии сохраняются. Баланс 0.4.0 и предел бонуса качества ×2 сохранены.

Для обновления закрой игру, замени DLL и сохрани настройки и оба файла цен. Серверная установка не нужна.

Compilation and automated checks passed; version 0.5.1 still needs an in-game test.

0.6.4 (local UI update)

• Slim quantity sliders: 2-unit rail/fill and 6-by-12 handle, with no pale handle outline.
• Fixed Unity's perpendicular handle stretching: the height delta is zero, so visible size is exactly the handle area's height instead of adding a second height.
• Added comfortable spacing below quantity buttons and above the item-slot bottom, while retaining a larger invisible drag area.
• Moved UPGRADE lower and reduced its height slightly; wheel-to-button clearance increases from 6 to 19 reference units.
• Added a separate bold red Russian/English recommendation at the top of NO LIMITS hover help: keep the mode off to preserve upgrade balance.
• Increased help popup space, separated recommendation/body, and prewarmed the new bold glyphs across frames.

• Added 30% / 50% / 70% presets using the configured chance curve and cap.
• Presets choose an eligible item and its best legal integer quantity, then randomize within a nearby group. Actual value multiplier and odds are displayed; selection never starts a roll or spends items.
• Quick selection respects character discoveries, obtainable-item filtering, real stack sizes and the NO LIMITS ceiling. Search/category filters do not narrow automatic picks.
• Added integer quantity sliders for both stake and reward, synchronized with buttons and the reward number field; controls are locked during spins and pending rewards.

• Switching back restores progression and one-stack rewards, clears undiscovered targets and clamps oversized quantities immediately.
• Added lower padding for RELOAD VALUES and more space between the wheel/needle and the header divider.
• Preserved prior rewards, price files, five-second spins, scrolling and the pooled catalog.

0.6.1

• Reward quantity defaults to one actual stack of the selected item, read from the game's item data.
• Added the top-left ONE STACK / ОДИН СТАК toggle, enabled on every player/world entry. Turning it off allows multiple stacks within the existing configured ceiling.
• Buttons and typed quantities share the per-item limit; the current reward limit is shown below the reward slot.
• Turning the limit back on clamps an oversized selection and recalculates its value and success chance immediately.
• The roll checks the quantity again before consuming the stake. The toggle is locked during spins and while a reward awaits collection.
• Previously earned rewards, custom values, progression, pricing and local-only operation are retained.

• Added slim draggable scrollbars; normalized mouse-wheel scrolling and the existing scroll-speed setting retained.
• Window scaling fits both axes, including ultrawide and 4:3 screens.
• Game Norse title font is reused when loaded and compatible with the translated title; unsupported glyphs use the existing body font.
