Warning! Mythic traits are a bit more powerful than most traits—this is intentional, as these traits help to set up a character’s mythic background! Mythic traits are intended for use with Mythic characters.
As a child, you were badly mauled by a demon. The demon was slain before it could kill you, but you lingered at death’s door for weeks before regaining consciousness. Ever since, you’ve been unusually hale and hearty, as if your body had reacted to its brush with doom by becoming supernaturally fit.
Benefit Once per day when you fail a saving throw against an effect created by a demon that would kill or incapacitate you physically, you can immediately reroll that saving throw as a free action. You must take the second result, even if it is worse.
