Hey guys!

I was also wondering about this because there wasn't any explanation inside the News threads. Therefore I wanted to share it with you guys.

It's located right next to the Rich Field server event, however it works only for lower level players (Up to level 70)

And its only purpose is actually leveling up faster.

You have a small fight which is free 4 times a day and you get some experience based on the damage you deal

Here are the in-game explanation rules. You need to be level 30-70 and do a few daily activities (60 daily activity points)

That's about it, nothing to special. Just a small feature for faster leveling
