The AFK system in Aurora Blade offers your character a chance to level up as well even if you are far away from your keyboard. Talk to the "Hotel Attendant" in the Dak of any cities to have a rest. It offers you a double exp scope which helps you obtain double exp while killing monsters. The higher the character level is, the more double exp you will obtain.

What's more, you can talk to the Priest in the church of any cities to enter the Temple and have a rest there. It offers your trinket a chance to obtain some exp directly. The higher your trinket level is, the more exp it will obtain.

Pay attention. The character should be online when it has a rest in the Dak or the Temple; otherwise, it cannot obtain any exp.
