What is this?
UMU Backpack is a simple mod that adds a backpack and some enchantments.
About backpack
To craft a backpack, you'll need 4 leathers, 2 rabbit leathers, and 1 gold ingot and 1 shulker shell.
Backpacks can also be dyed by crafting them with dyes.
You can open the inventory by pressing the B key while equipped with a backpack. Also, if there are items in the backpack, you will not be able to remove the backpack.
Enchantments
Cram
A regular backpack inventory only has 9 slots, but with the cram enchantment it grows up to 54 slots.
Back Protection
Reduces damage taken from behind when a player is equipped with a backpack with this enchantment. The maximum level is 4, which does not compete with other resistant enchantments.
Load
Instead of not being able to open the backpack inventory, small animals, such as chickens or cats, can be transported in the backpack.
