Legendary Backpack
Legendary Backpack is a Forge addon for storage players who want a single very large backpack that serves as endgame storage, and it runs on the client and the server.
What it does
The addon adds one ultra-large backpack with 154 inventory slots, placed above the increasing capacities that RPG Backpacks provides on its own. RPG Backpacks is required, so the base mod must be installed alongside the addon or the addon will not work. Curios API is optional; when it is installed, the backpack can be worn in a Curios slot, while without it the backpack works as a right-clickable storage item.
Crafting the Legendary Backpack takes high-tier materials, and players place a crafting table and a forge next to each other for the recipe. The backpack opens with a right-click, where items can be stored and sorted. Files are published for Forge 1.20.1 only, and the latest is 1.0.0, released on 2025-03-24. The code is covered by All rights reserved, so the mod is not open source.
Key features
154 inventory slots
A single backpack with 154 slots, the largest storage item the addon provides on top of RPG Backpacks.
Right-click storage
Opening the backpack with a right-click gives access to its contents, which can be organized directly from the screen.
Curios support
With Curios API installed, the backpack can be worn in a Curios slot, which keeps the inventory free for other items.
Crafted from rare materials
The recipe needs rare and valuable materials, so the backpack comes late in progression.

Use cases
Long adventures
Explorers and hoarders who travel far from base can carry supplies without returning to chests.
Late-game storage
Players who have reached the end of the progression can use the backpack as a storage hub instead of building chest rooms.
Who it’s for: Players on Forge 1.20.1 who already use RPG Backpacks and want a larger storage option, and server owners who want a high-tier storage reward for their progression.
How it compares
Vanilla Backpack is open source under the MIT License and runs on client and server for Forge 1.20.1, so it can be used as a lighter alternative. G's Backpacks is also a Forge 1.20.1 storage mod for client and server, but it is not open source and is covered by All rights reserved. TFC : Carry on Storage works on either side, and neither needs it, for Forge 1.20.1 under the CC0 1.0 Universal license.
