This is the most common question asked by many users that there is place on the screen call Campfire. And no one knows that what does campfire do. and how to unlock it. So here we will put some theory about what is it and what it might be.
Campfire is still under development I think and soon Plarium will open this area.
Campfire seems like we need to lit up the fire to get a certain type of bonus. like XP bonus, artifacts upgrade consumption reduction, energy refills speed, etc.
It will open for some special event/holidays. and rewards will as per event.
We will update the article once we have more info.
