One of my favorite bits from the original dishonored that they kept in the second one was the ability to complete the entire game without killing a soul. Dishonored had a non-lethal category so why not Dishonored 2? And maybe while you're at it add in a no powers mode category (Flesh and Steel%).
i asked on the discord for these to be added but it seems to have fallen on deaf ears. i expect they will soon as i think janmumrik the mod runs non lethal.
I know Janmumrik has been routing NLG (non-lethal ghost) for quite a while now, apparently it's really hard to route so just give it some time before someone actually comes up with decent strats i guess
Start running it and leaderboards will be added, it's usually how Chops prefers to keep his precious precious game pages.
