Alright, more testing.
A Life Or Death Situation is actually really funny: It will activate even during your turn and put you back into Still Stance. Unfortunately it doesn't reset your Draki's Perfect Scale when it does that so you can't chain infinitely.
If I serious about this build, yeah Subconscious is the way to go. Also probably worth focusing on dodge chance on your items just to maximise the amount of it triggering.
