Although bags are great way to get some extra space, you can only carry two bags at a time. If your backpack starts getting cramped, you can buy a bigger bag or improve your current one.

Runes can be applied on bags and increase their capacity permanently. Each bag can carry only one rune, if you use a new rune on a bag that already has one, it will replace the old rune. More information about the runes can be found on here.

You can further improve your bags by using Malachite Tablet. Malachite Tablet is a mysterious artifact, the magic of which allows you to permanently increase the number of places for artifacts in your backpack and can be used several times.

Each improvement will increase your backpack capacity by one, up to maximum of 10 extra spaces. You will need one tablet for the first improvement, however, each subsequnt improvement will require one tablet more.
