You can adjust the combat speed in the game. Different speed options help you adapt to various situations. For example, the x1 speed is convenient for manual combat mode and helps to control a battle more effectively. Meanwhile, the x5 speed lets you complete easy automatic battles more quickly.
The available speed options depend on whether your Valkyrie's Favor is active.
If Valkyrie's Favor is Not Activated
You can adjust the combat speed only in the Campaign, Tower, and Dungeon. You can set the x1.5 speed.
If Valkyrie's Favor is Activated
Active Valkyrie's Favor unlocks the x5 option in all combat modes. In the Campaign, Tower, and Dungeon, you can activate either x1.5 or x5 speed.
In other modes, the button displays only x5 speed.
