Dying

Dying

Occurs at any negative hit point total. You gain the Unconscious condition and can take no actions. At the end of each of your turns, you must make a Might check to see if you stabilize. The DC of the stabilize check is 15 + double your character level. If you succeed on the roll, you remain unconscious, but you stabilize and are no longer dying. If you fail the check three times in a row (over the course of three rounds), you die.

If you reach a negative hit point total of your CON stat (not stat mod) plus your level, you die. Most NPC's die when their hit points go below zero, but some NPC's only die when they reach negative their CON stat (not modifier) plus Level. NPC's cannot stabilize without some special ability such as regeneration or assistance from an ally.
