A 1v1 battle where players fight for one Treasure.

Secure one Treasure for a certain amount of time or KO all characters on the opposing team to win.

If time runs out, then the person who has secured the Treasure at the end of the battle wins.

If no one has secured the Treasure, then the person with the highest score wins.

Players who have reached League SS in League Battles can enter.

Head to Battle > 1vs1 Battles during the event period to enter.

You need to have four characters in your party in order to battle.

Each character has a cost.

Make sure to balance your party members so that their cost doesn't exceed your party's max cost.

There are seven classes in 1vs1 Battles.

Your 1vs1 Score will change based on the results of a battle. Win lots of battles to get your class promoted.

Changes to 1vs1 Score and Bonus values differ from League Score.

If you are promoted to a top class, you will acquire rewards and a special frame at the end of the season depending on your class at that time.

When swapping characters, the current battle character will be swapped out for a reserve character.

It takes a little time to swap characters, which might invite the risk of the Treasure being captured by the enemy.

Don't hesitate to swap your character when there's a standstill in battle or if things aren't going your way.

However, make sure you pick the right moment as the time it takes to swap characters will increase with each switch.

When swapping out a character, they will retain their max and current HP when they are swapped back in.

Swapped-out characters are not treated as KO'd, so KO effects will not activate.

However, effects that are lost or reset upon being KO'd (such as from Traits, Skills, Treasure Area Transformations, status effects, parameter stat buffs/debuffs) will be lost or reset when the character is swapped out.

Characters can be swapped out if the following conditions are met.

- When your battle character isn't moving, or when moving using the virtual D-pad (Does not apply when using a skill).

- When your character isn't immobilized.

- When you have a reserve character who isn't KO'd.

- When there are enemy character(s) on the stage.

If you obtain a frame in 1vs1 Battles, it can be used until the results of the next season's 1vs1 Battles are announced.

As of the Ver.90000 Update, your control settings in the Steam version have been reset.

Go to "Options" > "System" and select "Control Settings" to reassign your controls.

Rewards will be sent to your Gift Box.

If the rewards do not appear in your Gift Box, please try restarting the game.

The rewards have expiry dates.

- Please make sure to check the expiry dates from within the Gift Box.

The event period and details may be subject to change.
