The Mask Keeper is fought at the Peaks area of the Visages location, accessed by taking the path directly ahead of Blooraga. Note that it is only fought after defeating another boss, also called Visages.

You will also find the Mask Keeper inside the Endless Tower as the notable enemy for Stage 11, Trial 1.

The Mask Keeper can be a difficult fight if players did not defeat the Masks of Emotions before the battle. These three optional boss masks are in the Joy Vale, Sadness Vale, and Anger Vale, all within the Visages area.
Each Mask pertains to a specific emotion, and provides support by buffing the Mask Keeper and debuffing the party. Defeating each of them in their respective Vale will disable them during the Mask Keeper fight, making it easier.

The fight happens directly after the Visages Boss, with no break to heal your party. As such, it is recommended to heal as much as you can before landing the last hit on Visages, to have full HP for the next fight.

The Mask Keeper is weak to Fire and Dark Element attacks, so use these elements against it to make the fight easier. Maelle and Sciel excel with these elements, and so they are recommended for this fight.
