Progressive Core is a rather simple but big mod which adds a variety of valuable ores, tools, weapons, armor, accessories and machines to the game.


The ore system is as the mods name suggests progressive and each ore/alloy has a certain tier.


Tier 0: Wood

Tier 1: Stone, Flint, Leather

Tier 2: Copper, Tin, Iron

Tier 3: Bronze, Tungsten

Tier 4: Steel, Obsidian

Tier 5: Hellsteel

Tier 6: Titanium

Tier 7: Mithril, Orichalcum, Adamantite


To get to the next tier you need ores/alloy from the previous tier.


Ore generation, tool and armor stats as well as pretty much everything else is configurable in your config file.
