Alright, so I did every faction challenges except one and it's the Romani challenge where you have to kill 5 stalkers without getting stabbed. I am currently at 3/5. Does anyone have a tip to find a stalker easily? I tried free-running in Constantinople and fighting guards with my Templar Awareness at 100%, but the stalkers don't seem to come anymore (I finished the game). Is it better if I load a memory and just free-roam in it? Thanks!
