The arena is a place in any village and Angel City where many go to battle each other in order to gain a higher rank and tokens which you can use to exchange for items or EXP.
The openents list is made up of people from different levels which you battle to raise your rank and earn tokens. Once you battle the oponent, the person will have a large red circle over their image with the words defeted. The higher the level you are, the higher level your opponents will be. Once you defete all opponents in that row, you are allowed to choose a card from the left side that words similar to that of the exploration. It's a high chance that those cards carry specual armor that is only gained through the arena. Once all the cards have ben chosen, the opponent list will refresh automatically.
From the top, you may choose to cash in you tokens for prizes. Lucky Draw is for choosing a jar to break open. And Refresh, is to refresh to opponent list. But, you only get one refresh per hour.
