About BreedingUpgrades
From ThunderstoreGives offspring of your tamed creatures a rare chance to spawn with an extra star.
Breeding Upgrades
Breeding Upgrades introduces a simple mechanic to Valheim taming. Every time your tamed creatures procreate (live birth or egg), there is a rare chance (configurable) for the offspring to be born with +1 Star.
🐺 Dedication
> This mod was made for my friends, Chris and Shady, who spent two months searching for two-star wolves just so they could cheese Yagluth. Now you can build your animal army in the safety of the meadows.
Features
- Star Upgrades: Offspring have a percentage chance (default 5%) to gain a star level.
- Egg Support: Works for both mammals (Wolves, Lox, Boars) and egg-layers (Chickens, Asksvin).
- ServerSync Enforced: Configuration is locked by default and synced from the server.
- Configurable Limits: You decide the cap. Want more than 2 stars? (See Creature Level Mods below)
Compatibility
Creature Level Mods:
- ✅ CLLC (CreatureLevelAndLootControl) - Fully compatible. Breeding upgrades work as expected. Required for star levels above 2.
- ⚠️ Star Level Systems - Not compatible. This mod uses a different level assignment mechanism that bypasses the vanilla breeding level inheritance.
Creature Mods:
- ✅ Therzie's Monstrum - Tested and working.
- Should work with all mods that add standard tamable creatures or eggs, and whatever new creatures that will soon be added in the Deep North update.
Configuration
A configuration file is generated in BepInEx/config/dumba.breedingupgrades.cfg after the first launch.
| Setting | Default | Description | | :--- | :--- | :--- | | UpgradeChance | 5.0% | The percentage chance that a baby/egg will gain a star. | | MaxStarLevel | 2 | The hard limit for stars. If you are using CLLC, you can set this to match your CLLC config. | | Lock Configuration | True | (Server Only) If true, clients cannot modify these settings. |
