Pillars of Eternity · Combat survival
Endurance and Health
Damage affects both Endurance and Health; depleted Endurance knocks a character out, while depleted Health causes permanent death.
How it works
When an enemy damages a character, both Endurance and Health are affected. A character is knocked out when Endurance is drained, and Endurance regenerates after combat to a level based on Health damage. Being drained of all Health causes permanent death. The passage also says resting can recover lost Health and Endurance, along with certain abilities.
