What it does

Backpacks come in seven tiers, from Standard up to Obsidian, and each tier can be enabled or disabled. Stack upgrades multiply the number of items a bag holds per slot. A fluid or XP tank upgrade stores liquid or experience, and tank contents remain in place when the upgrade is removed. Backpacks can be given names and a custom display icon, and the Trinkets integration lets a bag sit in a trinket slot.

The mod also allows bags to be stored inside other bags, with a loop protection that stops a bag from holding itself. Every value, including per-tier limits, can be changed in the in-game ModMenu configuration screen. Death and burn behavior can be set in the global settings. A server running it needs every connecting player to have it too. Installation needs Trinkets 3.11.0 or newer and ModMenu for the config screen. It is released under the MIT License and is open source, for 1.21.11 only, with the 1.1.0 Fabric file as the latest build.

Key features

  1. Seven backpack tiers

    Bags range from Standard to Obsidian, and each tier can be switched on or off in the configuration.

  2. Fluid and XP tanks

    Tank upgrades hold water, lava and experience, which can be filled or drained by clicking a bar with a bucket.

  3. Compact item counts

    Slots holding more than 999 items show shortened counts such as 1k, 2k or 1M, and holding Shift reveals the exact number.

  4. Advanced item filter

    The Advanced Item Filter Upgrade provides 18 filter slots for finer control over what a bag accepts.
