Boon of Perfect Body - [Twilight Realms - Epic Boon]

Your body is in perfect health. You gain immunity to diseases. You don’t need to eat, breathe, sleep or drink to survive and suffer none of the frailty of old age, and you can't be aged magically. Any save to resist exhaustion is made at advantage. Your maximum HP is as if you rolled the maximum on each hit dice roll when leveling up. Your hit point maximum or stats cannot be reduced (by effects, game rules still apply). Finally, any healing you receive cannot be reduced or negated.
