copperboost
by KIM_MY
Copperboost, a NeoForge mod for 1.21.1, adds a meteorite ore and a survival progression path built around the metal it yields.
What it does
Meteorite ore generates in the underground layers, between Y=-64 and Y=44, with its density highest near Y=-9. Only one small cluster of one to three ore blocks is placed per chunk, which keeps the ore rare. Fortune applies to its drops, and smelted ore yields meteorite grains that feed equipment upgrades.
Meteorite metal supports a full set of tools and armor that can be upgraded at a smithing table. High-tier compressed-meteorite armor grants strong combat bonuses, including Resistance II and +16 max health, and carries built-in negative debuffs as the cost. A further smithing step produces lightweight compressed-meteorite armor that removes those penalties.
Copperboost requires Armour Rebalance and AttributeFix, and it can use Overflowing Bars when that mod is present. The mod is published for NeoForge only, with 1.0.0 as the latest file for 1.21.1, and it runs on client and server, so the server and every player need it. The code is released under the MIT License, and the project is not open source.
