In Team Arena, auto-battle will use units and skills in the sequence you arranged before match.
You will gain a medal after winning a match, and lose a medal after losing a match. Matches that result in a draw game will not effect your medal count.
There are 6 ranks in total: Bronze, Silver, Gold, Diamond, Master and Challenger; and there are 5 grades in each rank, except for Challenger.
You will be promoted to the next rank upon earning enough medals, but losing medals will also cause demotion.
If you quit the match or disconnect during combat, the match will be counted as a loss.
When an opponent is located, you will have 90 seconds to adjust your team before the match begins.
The Arena Committee will send rewards via in-game mail at the end of each day according to you rank at that time.
The Arena Committee will also send rewards at the end of each season according to your highest rank for the whole season.
