Compact Iron
by Gaboro030
Compact Iron is a Forge automation mod in which players craft Golem Forges that generate iron over time.
What it does
Resources generated by a forge can be used to upgrade it to the next tier, so production grows with the player's progress. There are 8 forge tiers, built from wood, stone, copper, iron, gold, diamond, obsidian and netherite, and each tier has its own production speed.
Higher tiers run significantly faster but cost more to reach, which is how the mod balances early and late game output. The forge's custom screen shows progress bars and time estimates, so a player can follow production without leaving the interface. A server running it needs every connecting player to have it too. It is published for Forge only, with one file for 1.20.1, and the license is All rights reserved, so the mod is not open source.
