Hyperdimensional Co-Op

Hyperdimensional Co-Op is a battle mode where you work together with another player to defeat the boss.

The other player who fights with you against the boss is called a buddy.
In Hyperdimensional Co-Op, your buddy does not count as the battle member or ally mentioned in abilities' activation conditions and effect range.

Hyperdimensional Co-Op Battle Rules

Unlike in other battles, you and your buddy will use just one character each to challenge the boss in a 2 vs. 1 fight.

You will win the battle when the health of the boss reaches zero.
You will lose if both players are defeated or time runs out. You can continue the battle even if one player is defeated.

Shield Condition

Hyperdimensional Co-Op bosses have a special shield.
Their shield will have the following effects:

- Reduce damage received
- Nullify knockback effect of Arts attacks
- Cannot be defeated

Deal damage to the boss to destroy their shield.
The shield's status is shown via the shield gauge on the top of the screen.

Since the shield will slowly repair itself, cooperate with your buddy to quickly take it down.

Strike Chance

When the shield is destroyed, a strike chance will occur.
The shield will lose its effects during a strike chance.

The boss' shield will recover over time.
The strike chance will end when the shield fully recovers.

Cooperate with your buddy during the strike chance, and defeat the boss.


Burst will occur when the boss' shield fully recovers during a strike chance.
Burst will knock back and immobilize players for a set period of time.


Players will generate a certain amount of aggro in relation to the boss.
The amount of aggro you have will increase when you act against the boss. The boss will target the player with the most aggro.


Tap the icon to taunt the boss.

If you taunt the boss, your aggro will increase.

Use this tactic to decrease the amount of attacks your buddy receives.


Tap your buddy's icon to assist them when they're under attack.
By doing so, you will push your buddy out of the way and earn a link.
You will also become the focus of the boss' attacks for a short period of time.
Abilities that activate with cover change will not activate with assists.

Dual Impact

If the boss' Strike Arts collides with yours, you will be able to prevent the boss from attack for a set amount of time.
You can extend this period up to four times by successfully flicking in the direction of the on-screen arrows.

While your buddy prevents the boss from attacking, perform a Dual Impact by landing Strike or Blast Arts to deal a large amount of damage.

Rising Rush

In a Hyperdimensional Co-Op Rising Rush, both you and your buddy will draw a card. It's a success if at least one is different from the boss' card.
If you and your buddy choose the same successful card, your Rising Rush will be more powerful than normal.

When Defeated

You can still support your buddy during battle when you're defeated. Doing so will recover your buddy's health and Ki.

Your support can be given at set intervals.

Hyperdimensional Co-Op Rewards

If you win in the Hyperdimensional Co-Op, you can earn limited-time rewards, bonus rewards, battle points, and more.

Limited-time rewards are received after completion and can only be obtained a certain amount of times per day.
The amount of limited-time rewards you can receive per day varies by event.

You'll earn a bonus reward on top of the limited-time reward if you clear the battle with a buddy you found using the search feature.
You will not obtain a bonus reward if you cannot receive any more limited-time rewards.

You will earn battle points when you clear a battle if you are affiliated with a guild.
You will earn more battle points if you clear the battle with another guild member.

You will receive rewards even if your buddy wins the battle after you're defeated.

Simultaneous Rising Rushes

When you activate your Rising Rush at the same time as your Buddy, the Boss will be unable to stop or evade the attack.
The Rising Rush can still fail if the Boss chooses the same card as both players, but if successful, it will deal more damage than a regular Rising Rush.
In the event that the Rising Rush fails, either your or your Buddy's character will be chosen randomly to receive a penalty.
