This Chaos-season-specific message is displayed when leaving the Edit Defensive Team screen or going to the Home screen if the defense team you have set does not fulfill the conditions to be used in Chaos season.
The following conditions apply to defense teams during Chaos season.
・ There cannot be more than one of the same Hero.
・ There can only be one Hero with a Sing or Dance skill per raiding party.
・ There can only be one Hero with a Savior skill per raiding party.
Please try the following, because your Chaos season defense team needs to be changed in order to get the alert message to stop displaying.
■ Things to try
・ Reform the defense team you will use in Chaos season so that it fulfills the above conditions.
・ In the Choose Setup feature, remove Chaos season from the list of seasons that use the setup you have currently selected.
Note: If the Choose Setup button does not display when you enter the Edit Aether Keep screen, it will display if you press the "More" button.
