- Prerequisites: Toughness, Con 14
You are able to continue fighting while at or below 0 HP. Your actions are not restricted while below the Dying condition but above the Unconscious threshold. If you reach the Unconscious threshold you instead may function as if you were above half your Constitution and Spirit score in negative HP.
When your negative HP reaches the point that you would take Mortal Wounds and potentially die, you still do so. If you take Non-Lethal damage while at negative HP, you will fall Unconscious when the nonlethal reaches an amount equal to half of your Constitution score, or your full Constitution score if you possess an ability such as Ferocity.
Finally, your HP multiplier is increased by 1.
