I found and cross-referenced every item put it into organized Verso's Drafts DLC checklists.
There are6 Flags, 15 Pictos, 10 Weapons, 4 Sidequests, 14 Haircuts, 6 Outfits, 2 Paint Cages, 3 Tints, 1 Perfect Chroma Catalyst, and 25 Grandiose Chroma Catalysts in this DLC.
I also made a detailed guide for all items, with images for anyone struggling to find a certain item needed for 100 % Completion
The checklist on game-checklists.com remembers your progress even without login or subscription
If you've ever wondered how these are created, you just run along the game taking notes for 7 hours
