ItemUpgrader

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.

| Setting | Default | |---|---:| | ReturnRate | 0.85 | | MaximumChance | 0.95 | | UpgradeChanceExponent | 1.25 | | EquipmentValueFactor | 0.60 | | CraftingMarkup | 1.05 | | MaximumRewardAmount | 1000 | | SpinSeconds | 5 | | ScrollRowsPerNotch | 2 |

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.
