so at first I was just trying to see everything I could do, I used a mix of stealth and force, had high chaos for first few missions, then I thought of trying that ability to turn enemies into ashes, and see what happens if I kill everyone but am always in stealth. So I got low chaos in a mission where I did that, even with high murders. The second time I did that, everything went exactly the same as the first, but apparently I had been seen since I didn't get ghost, even though I never heard anyone speak or the music play for someone seeing you, and the corpses found was like 5, even though everyone I killed turned to ashes, and I didn't knock anyone out. This sent me to high chaos, then in the sewer missions after you escape the assassins, I got constant chaos, even with basically taking everyone out with the crossbow and having their bodies disintegrate, I never triggered anyone's aggression or got a notice of being seen or caught in any way. I got low chaos in the mission where your at the ball, even though I had to just shoot the person in the face, since when I grabbed them, that music guy would prevent me from entering the basement. The whole party was in chaos but it still counted as low..
