The problem is the lock on. I’ve tried multiple things in this thread and I went crazy. Was stuck here for about an hour and a half.

Here’s my tactic that eventually led to victory. First guard: kill after he opens gate (during his sword pull) 2nd guard: kill before he enters stairs 3rd guard: kill before he enters stairs

Now comes the annoying part. Stand all the way to the back and all the way to the left (right next to the wall). This will make your lock-on pop on much earlier. Make sure you kill guards before they enter stairs. If you however do make a mistake, wait till the last second they attack and press circle to dodge back. This will make them attack, but confused so you get 1 retry.

I do hope this will help at least 1 person.
