Undead are the walking dead.

==Traits==

An undead possesses the following traits (unless otherwise noted in a creature’s entry). 

* No Constitution score, an Undead uses its Charisma modifier for Concentration checks, Fortitude Saves, and Hit Point calculations..
* Darkvision out to 60 feet.
* Immunity to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects).
* Immunity to poison, sleep effects, paralysis, stunning, disease, and death effects.
* Not subject to critical hits, nonlethal damage, ability drain, or energy drain. Immune to damage to its physical ability scores (Strength, Dexterity, and Constitution), as well as to fatigue and exhaustion effects.
* Cannot heal damage on its own if it has no Intelligence score, although it can be healed. Entropic Damage (such as an inflict spell) can heal undead creatures in some cases. The fast healing special quality works regardless of the creature’s Intelligence score.
* Immunity to any effect that requires a Fortitude save (unless the effect also works on objects or is harmless).
* Not at risk of death from massive damage, but when reduced to 0 hit points or less, it is immediately destroyed.
* Not affected by raise dead and reincarnate spells or abilities. Resurrection and true resurrection can affect undead creatures. These spells turn undead creatures back into the living creatures they were before becoming undead.
* Undead do not breathe, eat, or sleep.
