✦ What is Probably Backpacks? ✦
Probably Backpacks adds a complete tiered backpack system to your Minecraft server. Players craft backpacks from Leather all the way up to Netherite — each tier offering more storage and more upgrade slots.
Backpacks are equipped in the CuriosPaper Back slot and are visible on the player's back as a 3D model! This plugin is a CuriosPaper addon, hooking into the accessory system to provide a seamless experience with custom textures, real-time dyeing, and a powerful upgrade system.
[!IMPORTANT] This plugin requires CuriosPaper to function!
