When a creature dies under horrific circumstances or with an important task left unfulfilled, sometimes their spirit will not leave their body after death. The flesh may not (or may) decay, but their mind will – often consumed with the time of their death, these revenants will carry out a repetitive task for the remainder of their life.
Additionally, undead can be created as servants to certain magic users. These undead are not inhabited by the spirit of the creature that is animated, and as such have even less of a mind – often unable to communicate by any means other than groans and grunts, or perform tasks any more advanced fighting under a mindless urge to kill.
- An undead has no Constitution score and is immune to any effect that requires a Fortitude save. It uses its Charisma modifier for Concentration checks.
- Darkvision out to 60 feet.
- Immunity to poison, sleep effects, paralysis, mind-affecting effects, stunning, disease, and death effects.
- Immunity to non-magic weapons. Magic, psionics and fire effect them normally.
- Not subject to critical hits, nonlethal damage, ability drain, or energy drain, is immune to ability damage to its physical ability scores and is not at risk of death from massive damage, but when reduced to 0 hit points or less, it is immediately destroyed.
- Cannot heal damage on its own, although negative energy can heal undead creatures. Resurrection spells turn undead creatures back into the living creatures they were before becoming undead.
- Undead do not breathe, eat, or sleep and are immune to fatigue and exhaustion effects.
- Undead have an aura of fear that cause any living creature to become panicked. They are subject to a will save DC 10+ the level of the undead creature. This aura has a 10ft radius.
- Undead exposed to direct sunlight take 1 point of fire damage every round.
