Arena

Arena is a feature to impress fellow server players with the system of ranking not based on power charts. The more scores a player accumulates, the higher their ranking in arena chart.

Arena feature is unlocked when a player have 15 or more retainers and at least one of them has been level 60 or higher. Rank 10 unlocks Auto Battle similar to Vip 6 Auto Fight

In arena you are given one of your Retainers which is at least level 60 and you will have to try and defeat as many of your opponents' Retainers as you can. You are given option to purchase temporary ATTR for every round to help you do that.

To finish as many Retainers as possible turn on Auto Battle. Then it will automatically take weaker Retainers first(in terms of total attribute/hit points)

Usually opponent retainers have background color to intimidate you, as follows:

Log and Challenges
You can have 4 free Random Battles every day and then use War Tokens fight more times, once for every five retainers with Level 60+. If you defeat 20 opposition retainers or more you get on Log where other players can Challange you on battle with Challange Letters.That is why in Arena events try to not get on Log if you feel weak or want to avoid 'bullies' because other players will probably Challange you if they see you as 'meat' to munch on. With Hunt Tokens you can Hunt players by inputting their game ID. That means they don't have to be on Log for you to do that. Hunt Tokens will make your opponents lose scores 2x more but you won't get 2x more points. The score you get from Hunting others is the same as if you had used Challenge Letter or gotten them in Random Battle. Go back to Emperor and Beauties wiki page for other information.
