A configuration pack for ProbablyBackpacks that extends the default backpack progression to 21 backpack tiers + a unique Legendary Backpack, featuring balanced crafting recipes and a fully integrated DeluxeMenus interface.
Note This repository is not a plugin or a fork of ProbablyBackpacks. It is a community-made configuration pack that extends the original plugin.
Craft backpacks & upgrades directly from the GUI.
This expansion extends ProbablyBackpacks' default progression to a total of 21 backpack tiers, culminating in a unique Legendary Backpack that can be crafted using some of the rarest items in the game.
The Legendary Backpack is not part of the normal progression. Instead, it serves as an optional end-game goal for players seeking the ultimate storage solution.
Backpack capacities range from 27 slots up to 765 slots, allowing players to gradually unlock larger storage as they progress.
Each new tier builds upon the previous backpack, creating a balanced and rewarding progression.
Every backpack has its own crafting recipe designed around Minecraft progression.
Higher tiers require:
- Previous backpack
- Rare materials
- Exploration
- Nether progression
- End progression
- Advanced crafting
This prevents players from skipping directly to end-game backpacks.
Includes a complete GUI for backpack crafting.
Features:
- Two menu pages
- Easy navigation
- Material validation
- Automatic crafting
- Sound effects
- Error messages
- Previous/Next page navigation
Players never need to remember crafting recipes.
Everything is available through the graphical interface.
The menu also provides access to ProbablyBackpacks upgrades such as:
- Crafting Upgrade
- Pickup Upgrade
- Magnet Upgrade
- Feeding Upgrade
- Refill Upgrade
- Tool Swapper
- Compacting
- Furnace
- Blast Furnace
- Smoker
- Smithing
- Anvil
- Jukebox
- Stack Upgrades

The backpacks.yml recipe file is shared by both languages — the backpack item names it defines (e.g. Leather Backpack) are always in English regardless of which DeluxeMenus GUI language you install, since ProbablyBackpacks uses them internally.
Tested with:
- Paper v26.1.2
- ProbablyBackpacks v2.3
- CuriosPaper v2.0.0
- DeluxeMenus v1.14.1
- PlaceholderAPI v2.12.3
- CheckItem Expansion v2.7.9
- Player Expansion v2.0.9
Before installing this pack, make sure your server already has the following plugins installed:
- ProbablyBackpacks
- CuriosPaper
- DeluxeMenus
If you plan to use the included DeluxeMenus GUI, you must also install:
- PlaceholderAPI
- CheckItem PlaceholderAPI Expansion
- Player PlaceholderAPI Expansion
Without the CheckItem & Player expansion, the crafting validation inside the GUI will not work correctly.
You can install it using:
/papi ecloud download CheckItem
/papi ecloud download Player
/papi reload
The included DeluxeMenus interface is available in English and Spanish, each in its own folder (DeluxeMenus/en/ and DeluxeMenus/es/). Install only the folder matching your server's language — see Installation below.
The two versions are functionally identical: same recipes, same item requirements, same crafting logic. Only the GUI text (titles, lore, messages) differs.
You are free to translate the menu files into any other language by editing:
- gui_menus/probablybackpacks_menu.yml
- gui_menus/probablybackpacks_menu_page2.yml
Install ProbablyBackpacks.
Start your server once so the plugin generates its default configuration.
Replace:
plugins/ProbablyBackpacks/backpacks.yml
with the file included in this repository.
Choose one language folder — DeluxeMenus/en/ or DeluxeMenus/es/ — and copy its contents into your server's DeluxeMenus folder.
plugins/DeluxeMenus/
config.yml
gui_menus/probablybackpacks_menu.yml
gui_menus/probablybackpacks_menu_page2.yml
Do not mix files from both language folders — each one is a complete, self-contained set. Replace existing files if necessary.
Reload DeluxeMenus.
/dm reload
or simply restart the server.
The included DeluxeMenus configuration registers commands that open the backpack menu. The aliases depend on which language folder you installed:
English (DeluxeMenus/en/)
/backpacks
/bps
/bags
Spanish (DeluxeMenus/es/)
/backpacks
/mochilas
/tmochilas
/bps
Depending on your server configuration you may customize these aliases.
Instead of using the crafting table, players can craft backpacks directly from the GUI.
The menu automatically:
- checks required materials
- removes ingredients
- gives the crafted backpack
- plays confirmation sounds
- displays failure messages when requirements are missing
The default ProbablyBackpacks progression has been extended to a total of 21 backpack tiers, each requiring the previous backpack as part of its crafting recipe.
Each backpack tier includes its own balanced crafting recipe designed to match the progression of the game.
The complete backpack progression is shown below:
| Tier | Backpack | Slots | Upgrades |
|---|---|---|---|
| 1 | Leather | 27 | 1 |
| 2 | Copper | 45 | 2 |
| 3 | Iron | 54 | 3 |
| 4 | Gold | 81 | 4 |
| 5 | Diamond | 108 | 5 |
| 6 | Netherite | 126 | 6 |
| 7 | Emerald | 144 | 7 |
| 8 | Amethyst | 162 | 7 |
| 9 | Quartz | 180 | 7 |
| 10 | Prismarine | 198 | 8 |
| 11 | Echo | 216 | 8 |
| 12 | Ender | 243 | 8 |
| 13 | Dragon | 270 | 9 |
| 14 | Beacon | 324 | 9 |
| 15 | Ancient | 378 | 9 |
| 16 | Master | 432 | 9 |
| 17 | Supreme | 486 | 9 |
| 18 | Mythic | 540 | 9 |
| 19 | Divine | 594 | 9 |
| 20 | Infinite | 648 | 9 |
| 21 | Ultimate | 765 | 9 |
Note Each backpack tier requires the previous backpack as part of its crafting recipe, creating a natural progression from early-game to end-game storage.
Legendary Backpack
In addition to the main progression, this expansion includes a unique Legendary Backpack with 1080 slots, craftable through a special recipe that requires some of Minecraft's rarest materials.
All custom backpack recipes are defined in:
backpacks.yml
You can customize every backpack without modifying the plugin itself, including:
- Ingredients
- Crafting Shape
- Backpack Capacity (Slots)
- Display Name
- Lore
- Item Model
- Custom Model Data
