How to Upgrade Placed Item Vaults Without Losing Items

You do not need to empty your storage or tear down your factory layout to expand its capacity. Create Iron Vaults lets you upgrade placed Item Vault multiblocks directly in the world while keeping every stored item intact.

Choosing the Right Upgrade Item

There are seven material tiers above the basic Create vault: Copper, Iron, Gold, Diamond, Emerald, Obsidian, and Netherite. Because the mod includes 28 distinct upgrade items, you do not have to step through every single tier one by one. Instead, you can jump directly from your vault's current material to your desired target tier.

• Open your inventory and locate the upgrade item matching both your current vault material and your target tier.
• Hover your cursor over any upgrade item in your inventory and press W to view its Ponder tutorial scene and see how the tier transition works.
• Craft the corresponding upgrade item for your structure.

Applying the Upgrade

1. Walk up to your placed basic Item Vault or existing tiered vault multiblock.

2. Place the crafted upgrade item into your main hand.

3. Hold sneak and right-click any single block belonging to the multiblock vault.

The entire connected structure upgrades instantly to the new tier. Your multiblock shape, any applied dye colors, and all stored items remain completely safe inside the expanded inventory.
