Steel Age
by ChaoticJib
Steel Age adds steel armor and tool sets for NeoForge, made from iron ingots, coal or charcoal, as a step between iron and diamond gear.
What it does
Steel Age introduces steel as a crafting material, with armor and tool sets that craft from iron ingots and coal or charcoal and reach the same stats as diamond. A steel armor set costs 86 iron ingots in total, so it is an iron-tier progression step rather than a shortcut. Its recipes are revealed by learning the earlier iron armor set. The mod runs on NeoForge across 10 release versions, 1.21.1 – 1.21.10, and it works on client and server, so the server and every player need it. It is published under All rights reserved, not as open source.
Key features
Steel armor and tools
Steel armor and tool sets sit between iron and diamond in Minecraft's progression, using iron ingots and a coal or charcoal fuel source.
Great steel and nether steel
Great steel and nether steel variants extend the steel line, adding further armor and tool sets for later progression.
Recipes revealed by iron
The steel recipes are revealed once the earlier iron armor set has been learned, so the new gear follows the previous set.
