I was able to beat Cordelia way underpowered (I am 150-160 right now) because she didn't move at all. She took all of my blows without even evading. The ragdoll wasn't broken, her body still reacted to my hits but nothing more. I was able to get her dagger (I had auto loot skill) and the event was registered but the challenge didn't register. It still says 2 out of 3.
