Overview
How to dodge kill, not dodge stun, so you can (hopefully) figure it out before the end of the game.
The Way To Do It
When you unlock the dodge kill ability, it seems powerful in concept, but it (from my recollection) does not specify how to dodge kill and dodge stun. What I notice is that, when the middle circle’s icon flashes (sometimes twice), the circle that shrinks will begin to expand. After the circle begins to expand, press F as it indicates.
