HardenedCore
HardenedCore makes Minecraft early game feel more deliberate and rewarding by removing shortcuts that experienced players skip anyway and replacing them with a coherent progression system.
Changes
Tools
Wooden and stone pickaxes and axes are gone, along with all stone tier tools included. Instead, craft a Flint Pickaxe from flint, this bad boy mines at stone tier and is your primary early game tool. Flint axes are also available as a crafting alternative to wooden axes. Wooden shovels, swords and hoes are untouched.
Ore Fragments
Mining all stone tier ores with a flint pickaxe drops a raw ore fragment instead of the usual ore. Fragments smelt in a furnace into a single nugget.
Blast Furnace
Raw ores and ore blocks cannot be smelted in a regular furnace at all. A blast furnace is required for ore smelting. This makes the blast furnace a meaningful milestone rather than a late convenience.
Progression Path
- Collect flint from gravel
- Craft a flint pickaxe
- Mine ores and collect raw fragments
- Smelt fragments to nuggets
- Accumulate 45 nuggets for 5 iron ingots to build a blast furnace
- Normal iron progression resumes
Mod Compatibility
- Ore blocks from other mods are automatically blocked from furnace smelting if they use conventional tags
- Tin ore fragment support included out of the box for Bronze mod
- Modpack authors can extend
hardenedcore:crafting_blacklistandhardenedcore:furnace_blacklisttags to add custom compatibility
For Modpack Authors
Two item tags control recipe removal at load time:
hardenedcore:crafting_blacklistincludes items whose crafting recipes are removed entirelyhardenedcore:furnace_blacklistincludes items that cannot be smelted in a regular furnace
Add any item to these tags in your datapack to extend HardenedCore's restrictions to modded content.
