Arena

* To play the Battle Arena, a player needs to unlock it first.
* Battle Arena is automatically unlocked when  'Collecting Data' on the Prologue Stage reaches 100%.
* The 'Collecting Data' can be finished by playing the 'Prologue Stage'. A higher difficulty gives a player more data. Re-playing the sections also allows a player to get the data and a player can acquire more data by using AP boost.

### Arena Rank

* There are 4 skill tiers. Bronze(0 ~ 1999 Pts), Silver(2000 ~ 3999 Pts.), Gold (4000 ~ 5999 Pts.), and Top Class(6000 Pts or over).

* From Bronze to Gold, each tier has scales of 1 ~ 10 and there's a 200 score difference between each scale.
* Each Arena season lasts a week. Starts at 00:01 every Monday and ends at 22:00 every Sunday.
* After the season ends, a player may receive rewards depends on the player's last tier.
* Win streaks or winning a match against a player whose Team CP is higher than yours gives you more scores.
* When a player is defeated, the player will lose his/her scores. However, scores will not go below the minimum requirement of a player's current tier.

### Match

* A player can join the Battle Arena through 'Matchmaking'. Each matchmaking requires a certain amount of gold and 1 BP.
* The match automatically proceeds. Characters fight on their own and even a supporter skill can be used automatically. However, a player can manually use 'Cheer', which grants certain buffs(i.g. Movement speed, HP regeneration.), and the supporter skill can also be used manually.
* The more a player's win streaks go up, the stronger the opponent's Team CP will be.

### Character Set

* Players need to set characters(Taimanins) to attend the Battle Arena.
* Basically, the Battle Arena requires 3 characters. However, it's possible to attend the Battle Arena having less than characters.
* Set consists of 1st Pick, 2nd Pick, and 3rd Pick(or, Commander).
* Characters can't be set if the next pick(or, slot) is empty. Therefore, if a player has less than 3 characters, it's wise to set the 3rd pick(Commander) first, and then the 2nd pick.

### Battle Score and Arena Coin

* If a player wins a match, the battle scores positive points.
* Losses lower score, unless already at the minimum score for previously earned rank.
* Arena coins are acquired even if you lose.
* Defeating higher score opponents, gives greater score increases (similar system for defeats).
* The higher your score the greater the arena coin rewards.
* Wins on 1st pick or 2nd pick can give you more score and arena coins.
* Crest bonuses stack additively and fractions of arena coins acquired are rounded down.
* For 5000 gold (less with crest effects) a player may double the arena coins earned.
* Tablets of ATK and HP used will add 25% more arena coins and provided other listed bonuses to team and score gains for one match.

### Arena Store

* Players can use the Arena coin in the Arena Store.
* Players can buy Commander Mark, Crest Gacha, Materials for Crest enhancement and reset, tablets, and weapons.
* Players can unlock the higher store by achieving the higher tier.
* The higher tier store includes the lower tier store.
