Arena

In the arena, players can fight each other for the highest rank and better rewards.

Attack and defense
Once you set up your defense (by clicking the change button at the bottom), you can select an enemy to attack. The first time you open the Arena, you will be directed to click on the NPC Metamorphosis, the team of Metamorphosis composes of a level 6 white (1 star) Aurora, a level 4 green (1 star) Fox, and a level 5 green (2 star) Arachne. If you are feeling that the enemy is too strong, you can press the refresh button on the left. When you press the attack button, a screen will pop up with all of your heroes. Select your heroes to fight against the enemy, then click on the battle button.


 * Each successful attack grants 20 Arena Coins
 * Each successful defense grants 10 Arena Coins.

Previous battles can be found in the Arena Log.

Rules
From in-game.


 * 1) Battles are fought in automatic mode.
 * 2) When you defeat an opponent, you take their place in the ranking.
 * 3) If there is no winner after time runs out, the defending player wins.
 * 4) After a battle in the Arena you can't fight for 1 minute.

Matchmaking
Each player can select three different enemies depending on the current position and the matchmaking range. The target rankings are selected based on offsets and a random part.


 * Target rank 1 = Current position - offset 1 +- random
 * Target rank 2 = Current position - offset 2 +- random
 * Target rank 3 = Current position - offset 3 +- random

The Retarget offset additional applies if you lost your position during selecting your target, probably, difficult to test but value exists in the game files.

Because at some point the matchmaking ranges change it is advantageous to attack the left target if you are near one of these ranges, for example, both ranking 520 and 470 have the same left-most target position!


 * Position 520 -> Target ranges: 420 +-5, 470 +-5, 510 +-5
 * Position 470-> Target ranges: 420 +-5, 440 +-5, 460 +-5

Rewards
You will get your daily reward if you fight in the Arena or Grand Arena at least once that day. If you have a higher ranking on the Grand Arena than the Arena, you will get your reward for your Grand Arena ranking.
