Confine & Remove

Marona has the power to control Phantoms. The act of her causing those Phantoms to possess items and materialize is called "Confine." Ash and other Phantoms can only join in the battle through this.

In battle, basically all characters other than Marona are Phantoms without bodies. You can make these phantoms haunt objects on the Map and join the battle. This is called "Confine."

However, the period of time each character can haunt an object is quite short. After several turns, the Phantom will leave the "vessel" and return to their homes. This is called "Remove."
