how do i unlock the codex pages and also how do i get the perfect harmony achievement . where can i get the wetland ebony and wetland ivory tints
Wetland Dyes are available once you get to Venice.
codex pages can be found by looking at the map. when your in the general location, get on the ground. there will be a doorway with about 3 guards blocking it. u could kill them, or hire a group of thieves/hookers to distract them. theres almost always a group by them though so its easy. bring it to leanardo when u have it
