Backpack is an inventory organizational tool. You need to open the backpack to view any items placed inside. This also makes it harder to see everything you have at a glance. Some players prefer to simply use the filter buttons on their inventory to narrow down what they are looking at rather than use backpacks or pouches, as they find containers actually make it harder to manage inventory.
Where to find:
- Sold by Merchants
