Crafting and Finding Backpacks

All backpacks start as a Standard Backpack. Then you can use the Standard Backpack to make a different one. The recipes can be seen in game using NEI or another recipe visualizing mod.

When you craft a Standard Backpack into another one, you will lose whatever the backpack contained, so better empty it out first.

When you craft a Dragon Backpack you get your Dragon Egg back.

Some backpacks are not craftable:

• Villager Backpack can only be acquired by buying it from a Priest or Librarian villager.
• Electric Backpack can only be acquired by wearing a Diamond Backpack and being struck by lightning.
• Pigman Backpack can be acquired one of two ways: By finding it in a desert temple (if you enable the config option for that), o by wearing a Pig Backpack and getting struck by lightning.
• Iron Golem Backpack can be found in some chests inside a Blacksmith's House in a Village.
• Bat Backpacks can be found in dungeon and mineshaft chests.
• Sponge Backpack is kinda creative only (in 1.7.10), unless you have another mod that let's you obtain Sponges in survival. It can be crafted though.
