Undead share the following additional traits.

Weapon and Armor Proficiency: Undead receive either Archaic Weapons Proficiency or Simple Weapons Proficiency as a bonus feat. An undead is proficient with its natural weapons and any weapon mentioned in its entry. Undead noted for wearing armor gain the bonus feat Armor Proficiency with whatever type of armor they are accustomed to wearing (light, medium, heavy), as well as all lighter types.

Ability Scores: An undead has no Constitution score. It uses its Charisma modifier for Concentration checks.

Darkvision (Ex): Most undead have darkvision with a range of 60 feet.

Immunities: Undead are immune to poison, sleep, paralysis, stunning, disease, necromantic effects, and mind-affecting effects. They are not subject to critical hits, nonlethal damage, ability damage, ability drain, energy drain, or effects of massive damage, or any effect requiring a Fortitude save unless the effect also works on objects or is harmless.

Healing: Undead cannot heal damage on their own if they have no Intelligence score. Undead can be healed with negative energy (usually only available through the use of magic). Most undead are destroyed immediately if reduced to 0 hit points or less.

Special: Undead cannot be raised from the dead.
