Arena is a unique game mode in which players use their current Hero system to compete against other players for glory and rewards.
Each participant in the Arena can bring up to three heroes with them. Battles will take place in a turn-based system, pitting two players against each other.
The combat will conclude when either player's heroes are destroyed or the match timer runs out. If the match ends due to a time limit, the hero party member with the highest percentage of remaining HP wins.
Similar to the Tournament game mode, in Arena there is also a rank system to rank players as well as the rewards they receive. The player who wins each battle will receive the corresponding reward and Elo points, while the player who loses will not receive the reward and forfeit Elo points.
