What is ranking about in the Arena?

Rankings are decided by the number of points you acquire in the Arena.
Winning consecutively and using units with bonuses will earn you more points.
*You may view the details of the Unit Bonus by tapping on Duel > Arena > Unit Bonus
*Only the highest value of identical Unit Bonuses will be applied.
Example: If you have a unit with a Bonus +100% and another with a Bonus +75%, only the Bonus +100% will be counted.
