Using Yrden near the pillar at the middle is also a good strategy if you can position yourself behind it and the pillar but a little to your right/left - ready to make a circle just in case. There seems to be a bug here - exploit maybe? If you do above properly, it'll appear like the Koschey doesn't see you and would walk around aimlessly (like it's not pursuing you).

Quen helps while drinking potions. I didn't know about the wall tactic but I fired Igni at it like a couple of times - while mainting distance with the Yrden and the pillar between us.
