About this project
What does Copper Tools Expanded add?

A mod aiming to expand and improve copper by adding tools, equipment and more items with unique properties and uses!
Copper Utility
Apart from the tools, weapons and armor added by the mod we also have additional utility.
- Barometer: Can be used to view current weather, predict next weather, and see when weather will change.
- Copper Shields: Used like normal shields, but has different speed penalties.
- Copper Apples: Like a Golden Apple it will give you effects when eaten, but copper is toxic so you get a mix of positive and negative effects.
Oxidation
Copper tools start oxidizing when exposed to water. Either when in water blocks or while standing in rain. Oxidation has 4 stages, and each stage gets different tool values (Like damage, durability, swing speed, etc) and properties!

Waxing
Copper tools can be waxed to lock the oxidation stage in place. This will make the tool keep its oxidation stage until manually unwaxed.

Planned updates?
- Near future:
- 1.21.4 - 1.21.11 ports
- Future:
- Fabric 1.21.1 - 1.21.11 ports
- Continued updates for 26.1+
1.17.1 - 1.19.4 will for the most part remain unchanged. I won't keep up parity but might add smaller features and bugfixes
