Upgrade to a Better Backpack
Know When to Upgrade
As you progress deeper into mining, your current backpack will feel cramped. Iron and gold backpacks offer more slots than copper and coal. Emerald, diamond, and netherite bags are designed for end-game mining when you're collecting massive quantities of resources.
Gather Upgrade Materials
Mine the ore corresponding to your target backpack tier. Iron requires iron ore from stone or deepslate. Gold needs gold ore from deeper levels. Emerald, diamond, and netherite require mining in the deep underground or nether. The special mineral tier requires the rarest crafting material in the mod.
Craft Your New Backpack
Once you have enough material, craft your upgraded backpack at a crafting table using the same bundle-shaped recipe. Your old backpack can be stored or repurposed.
Transfer Your Items
Open both your old and new backpack. Drag items from the old backpack into your inventory, then into the new one. This gives you more storage space for your next mining expedition without losing your collected loot.
