Hello!

To clear this topic about Zenith. Zenith is open every last 5 days of each month, and that's 4 days to compete with players and earn points and the 5th day is for the championship where only players who get 8 points can enter. Each day, you can participate in 4 battles but it is not suggested to do it all in one day, you can plan on doing it by 2 battles per day. Lastly, Zenith is open every day from 18:00 up to 21:00 Server time.

I hope this brings enlightenment to the author of this thread. Thank you.
