Illusion is hilariously overpowered and underrated in that game (once its leveled up higher). I rushed max pickpocketing, then pickpocketed back the money from the illusion trainer at the college.
Theres also invisibility and dagger fighting; holding invis without releasing it makes it trigger after you swing
I dont think i even finished the tutorial for Syndicate, it was so bad. No human being is that fucking spongy and taking 20 something punches to the face, and like you said, why is an assassin punching people!?
