If a character has died and was brought back to life, they may be afflicted with the PTSD "feat". If a potential trigger is encountered, they must make a DC 10+CHA mod constitution saving throw.
If the trigger is loosely related, i.e. seeing a cliff after dying from one, they make the roll with no advantage or disadvantage. If they succeed, no effect occurs. If they fail, they are considered frightened. Racial traits that prevent or give advantage against being frightened do not apply.
If the trigger is moderately related, such as having to jump a long distance down after a falling death, they make the roll with, again, no advantage or disadvantage. On a success, they are considered frightened for 1d6 minutes. On a fail, they are paralyzed for 1d20 seconds.
If the trigger is directly related, such as being the target of a shove attack after dying from one, they make the roll with disadvantage. On a success, they gain an extra damage die against the trigger, but take 1d4 levels of exhaustion after the trigger dies or leaves the area. On a fail, they attack anyone who comes near them, friend or foe, until they reach 0 hp, 1d6 hours have passed, they succeed in a DC10+proficiency constitution saving throw, or another character rolls a DC25-charisma modifier persuasion check.
