Paris Flying Papers Locations
This one can be found near the Wooden Bridge in the south of Paris. You’ll be chasing it over some rooftops to the east until you reach the small chapel in the northeasternmost part of the Flooded Slums. The paper will stop on the roof of this chapel, so you can actually just run there if you want to wait for it, then collect it without having to jump over the roofs. Collecting the paper provides you with the Mendicant Scheme (Back).
North of La Greve
This one can be found in the north of Paris, just north of La Greve. If you approach the paper from the north you’ll be chasing it eastward toward the docks. This provides the easiest route, giving you plenty of time to catch the paper before it reaches its final destination on a rooftop overlooking the docks. The paper provides the Oriflamme Scheme (Head).
