After the buff to Lumina this season, I wanted to make a build with it and make it look cool with its ornament from season of Opulence. You can just go to the appearance part of a weapon screen and buy the ornament right there normally but didn't see it for Lumina. I go to the Archive part of the eververse and I see all other season 7 (Opulence) weapon ornaments except for Lumina. I dont know why that is but would just like to have it.
