Remember to keep your items in a safe because during the beta a craft system will see the light of day. It will create the objects you need to improve your gaming experience or your builds. As for example the creation of certain specific powers, like projectiles, combat improvements, passive powers etc. Other objects will be found only by crafting them, such as bags and cases. Some bags may increase the number of slots available in your inventory, while others may for example contain all of your scrolls, runes and gems (which will be released during the beta).
