WeaponCrafting Mod
A comprehensive Valheim mod that introduces a persistent Smithing skill system with XP progression, item stat bonuses, master-forge mechanics, and special boons.
What the Mod Does
Smithing Skill System
- Persistent leveling: Your smithing skill is saved per player and persists across server sessions
- Skill range: Level 1-100
- Auto-apply: Crafted items automatically receive stat bonuses based on your smithing level
XP Sources
Gain Smithing XP by:
- Feeding Kilns - +5 XP per wood item fed
- Feeding Smelters - +10 XP per ore/coal item fed
- Feeding Blast Furnaces - +15 XP per ore/coal item fed
- Crafting at Forges - +13 XP + 2×forge level
- Crafting at Black Forges - +26 XP + 4×forge level
- Upgrading Items - +8 XP + 2×forge level or +13 XP + 2×black forge level
Item Modifications
All crafted items receive automatic stat boosts:
- Durability bonus: +5-10 base + (skill÷3)
- Weapon damage bonus: +3-6 base + max(2, skill÷5) per damage type
- Armor/block bonus: +4-7 base + max(2, skill÷4)
Master-Forge (40-60% chance by level)
When an item is master-forged:
- Durability: +20 additional
- Damage: +5 to all damage types
- Armor/Block: Enhanced (varies by boon type)
Master-Forge Boons
Special abilities applied to master-forged items:
Weapons:
- Razor (40% chance): +25% damage to all damage types
- Ogre (40% chance): +75% attack force
- Goblin (20% chance): +15% attack speed (at equip time)
Shields:
- Stalwart (50% chance): +60% block power
- Sealed (50% chance): +35% armor
Armor:
- Reinforced (60% chance): +25% armor
- Feather (40% chance): +3% movement speed (at equip time)
How XP Works
XP Progression (Non-Linear Exponential Curve)
The mod uses a forgiving exponential curve for skill progression:
Formula: XP required for level n = floor(80 × 1.05^(n-1))
Examples:
- Level 1→2: 80 XP
- Level 10→11: ~103 XP
- Level 20→21: ~132 XP
- Level 50→51: ~427 XP
- Level 75→76: ~1,086 XP
- Level 100: ~59,000 total XP
Why This Curve?
- Early levels: Quick progression to feel rewarding
- Mid game: Steady XP gain matches crafting pace
- Late game: Challenging but achievable with regular play
- Forgiving: No massive level gates like linear progression
Total XP to Max
Approximately 59,000 total XP to reach level 100 (doable with ~500-600 crafts or equivalent feeding).
Data Persistence
Smithing data is stored in JSON format:
{BepInEx config path}/weaponcrafting_smithing.json
Format:
{
"Players": [
{
"Name": "PlayerName",
"XP": 1234,
"Level": 15
}
]
}
Data is automatically saved:
- When you gain XP
- When the mod unloads
Installation
- Place JotunnModStub.dll in your BepInEx plugins folder:
{Valheim}/BepInEx/plugins/
- Requires:
- BepInEx 5.x or later
- Launch Valheim
Debug Logging
The mod outputs detailed logs to the BepInEx console:
- Kiln feeds: [WeaponCrafting] Kiln fed by PlayerName: +5 XP
- Forge crafts: [WeaponCrafting] Craft on forge level 2: +17 XP
- Upgrades: [WeaponCrafting] Upgrade near forge level 1: +10 XP
- Master-forges: [WeaponCrafting] Master-forged: PlayerName -> SwordName (boon: Razor)
- RPC broadcasts: [WeaponCrafting] Broadcast master-forge RPC: PlayerName -> ItemName
Multiplayer Notes
- Each player has their own independent Smithing skill
- Master-forge messages are broadcast to all players on the server
- Forge level detection respects actual forge upgrade levels (including black forges)
- XP is awarded client-side but persisted server-side for integrity
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
Install these first, or the mod will not work:
