Bag

Bags are equippable items used to increase inventory space. A bag holds up to 5 items. A bag's capacity can be increased to 10 slots if a Rune of Holding is applied to it. A character may have up to two bags equipped at once.

Bags, like backpacks or belt pouches, can be dyed, but will change nothing but the inventory picture. A bag's natural color is brown.

You can unequip a bag by dragging and dropping it into an inventory slot, provided it is empty.
