Before a fight with an intelligent being capable of communication begins. You will have a 5-second window to initiate dialogue with said opponent. Where both you and your opponent will be unable to attack or affect each other during said time.
After the 5-second pass, you will gain an increase in speed and defense for as long as you do not attack your opponent. (This includes physical, mental, and spiritual attacks.)
If your opponent is absolutely set on killing you, and their mind won't be changed through dialogue alone, then this perk does not activate.
Sneak attacks aimed at you also bypass this effect. However, after a failed sneak attack upon you, you can activate this perk if you did not launch a counter-attack.
You can turn this perk off if you desire.
