Feel free to take them out - Domino and a sleep dart works best - but you shouldn’t encounter them and they’re not going to be a problem in a minute. There are two more witches lounging on the first floor. The best approach we found was to Domino them together, then use the bookcases to repeat the drop attack on the one that is patrolling. Use the giant stuffed owls to get a better angle on them if you have to. There’s another hanging out on top of some bookshelves just over the railing. The first is patrolling on the opposite side of the Oraculum. There are two more witches to handle before we explore much more. You’re actually right across from the front entrance of the Royal Conservatory, but since when do you ever use the front door? Use the balcony on the other side of the abandoned lecture hall to get a little further down the road. The combination you bought/stole from the black market can be used here - there’s some ammo and about 400 coins inside. There’s a bonecharm and a painting in the office on the left, as well as a safe. It’s important to note here that nest masters do count toward your body count, so avoid killing him.

Clear out the bloodfly nests and knock out the nest master. Far Reach across the alley into the bloodfly-infested abandoned lecture hall on the right. When you’re done with the Outsider and the Void, get back to the roof. Check our collectibles guide for details.

There’s an Outsider Shrine in the blue building behind you. Knock out at least the guard, then turn your attention to the nearby buildings. Loot the ground floor - there’s a bonecharm down there - then head upstairs to the roof. Use the door on that landing to enter the building.

Use the landing to on the left to get above them and take them out. Continue along the path until you come to a corner where you can hear two guards talking.
