About this Mod

Mod Logo

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!

Shielding - Showcasing Oxidation

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.

All sets of tools and armor in the game!
