By near perfect I mean there is one part where I broke stealth and had to resort to my bow but quickly got the situation back under control. After assassinating everyone in the fort watch how I sucker the hit sponge boss guard into a blind alley and take him out with a ballista mounted on the wall for an easy no damage taken kill. Then I could just walk around the fort and loot everything and rescue Harkuf unimpeded ..... Your brain is your most deadly weapon
