Only one hero of your team can fight, but you can swap other heroes on standby.
When the Hero on standby appear in the field, the Hero's Strike skill will be activated.
① Tap the Hero you want to swap to.
② The Hero appears in the field and the Hero's Strike skill will be activated at the same time.
③ The previous Hero you swapped from will go back to standby, and you may change to them again after 14 seconds.
※ The guide was produced in a separate test environment.
So, It may change depending on the update and development situation.
