Am I the only one who did this in one go? Did a no armor run and just made these guys fall to their deaths with heavy blows.
Not at the first go, but eventually I realized it's easier if you just go lightweight and roll through the arrows, taking advantage of the longer invincibility frames. Blocking those arrows consumes way too much stamina and will break even the most stable guards. And once you manage to get close to the archers, just goad them into falling down the wall.
It wasn't hard for me at all. All you had to do was lure the one on the right and run back and it'll eventually fall off the building chasing you I'm pretty sure. It's been forever since I played the first Dark Souls.
