Copper Tools Expanded
by AlexisAngel
Copper Tools Expanded adds copper tools, shields and apples that change over time, with copper tools oxidizing through four stages.
What it does
Copper tools in the mod oxidize through four stages, and each stage changes their attributes. A shift in the weather can also change how they behave, and a player can read the current weather or predict the next change from the mod's tools. The copper shield is held like a regular shield, though it carries different speed penalties. Copper apples work like golden apples: eating one applies effects, and because the effects mix positive and negative ones, the result is less predictable.
The mod is a client and server mod, so the server and every player need it installed. It is released under the Apache License 2.0, but the code is not open source. Files are published for Forge and NeoForge across 17 release versions, 1.17.1 – 1.21.10, with 1.2.2 for 1.20.1 as the latest Forge file and 1.2.4 for 1.21.4 as the latest NeoForge file. The author notes a plan to port to Fabric 1.21.1 and continued updates after the current release; none of these are available yet.

Use cases
Weather-based planning
A player can check the weather before a trip, since the tools' behavior depends on it.
Combat with shields
The copper shield suits players who want a shield with a speed trade-off instead of the vanilla one.
Who it’s for: Players who want copper equipment with time-based and weather-based behavior, on Forge or NeoForge servers and clients.

What the author says
A mod aiming to expand and improve copper by adding tools, equipment and more items with unique properties and uses! 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
