Default Behavior
By default, the mod applies the following rules:
- 25% chance for a durability event to consume durability.
- A maximum of 1 durability can be consumed per durability event.
This significantly increases the average lifespan of equipment while preserving vanilla gameplay mechanics.
Configuration
The configuration file is automatically generated at:
config/unified_durability_tweaks.json
Default configuration:
{
"enabled": true,
"durability_loss_chance": 0.25,
"max_damage_loss": 1
}
Parameters
| Option | Description |
|---|---|
enabled |
Enable or disable the mod. |
durability_loss_chance |
Probability that a durability event actually consumes durability. |
max_damage_loss |
Maximum durability consumed per durability event. |
Multiplayer
This is a server-side mod.
- ✅ Dedicated Server
- ✅ Singleplayer
- ✅ LAN Worlds
Clients do not need to install the mod.
Compatibility
- Minecraft 1.21.1
- Fabric Loader
Designed to be lightweight and suitable for both vanilla+ gameplay and large modpacks.
How It Works
Instead of modifying weapon or armor attributes, the mod intercepts durability loss events and applies two configurable rules:
- Whether the durability loss should occur.
- The maximum durability consumed by that event.
This keeps the behavior simple, predictable, and compatible with vanilla enchantments such as Unbreaking and Mending.
