Talk: Unique skill

Should skills unique to bosses be included? I started adding all the ones for Persona 5/Royal after seeing Noah's skill Aurora added to the Nocturne section (will continue working on the rest when I have time) in a separate tab, however trying to add all of them will be a lot of work. I personally think they should be added, seeing as they are a skill signature to a certain character, however them not being usable by the player might be reason enough to warrant removing them from the page.
