Wights

Wights are undead.

Undead are once-living creatures animated by spiritual or supernatural forces.

They have darkvision.

Undead have immunity to all mind-affecting effects (charms, compulsions, morale effects, patterns, and phantasms).

They have immunity to bleed, death effects, disease, paralysis, poison, sleep effects, and stunning.

Undead are not subject to nonlethal damage, ability drain, or energy drain. They are immune to damage to their physical ability scores, as well as to exhaustion and fatigue effects.

They cannot heal damage on their own if they are unintelligent, although they can be healed. Negative energy (such as an inflict spell) can heal undead creatures. They may have fast healing regardless of the creature’s intelligence.

They have immunity to any effect that requires a Fortitude save (unless the effect also works on objects or is harmless).

Undead are not at risk of death from massive damage, but are immediately destroyed when reduced to 0 hit points.

They are not affected by raise dead or 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.

Wights are humanoids who rise as undead due to necromancy, a violent death, or an extremely malevolent personality. In some cases, a wight arises when an evil undead spirit permanently bonds with a corpse, often the corpse of a slain warrior. They are barely recognizable to those who knew them in life; their flesh is twisted by evil and undeath, the eyes burn with hatred, and the teeth become beast-like. In some ways, a wight bridges the gap between a ghoul and a spectre – a warped animated corpse whose touch steals living energy.

Wights sap a living opponent’s vital energy automatically when they slam them. Each successful energy drain bestows negative levels. If a wight scores a critical hit while slamming, it bestows twice the number of negative levels. A wight gains temporary robustness from each negative level it bestows on an opponent. Negative levels remain until 24 hours have passed or until they are removed with a spell, such as restoration. If a negative level is not removed before 24 hours have passed, the negative level may go away with no harm to the creature, or the negative level may become permanent.

As undead, wights do not need to breathe, so they are sometimes found underwater, though they are not particularly good swimmers unless they were originally swimming creatures such as aquatic elves or merfolk. Underwater wights prefer low-ceilinged caves where their limited swimming isn’t as much of a liability.

Any humanoids creature that is slain by a wight becomes a wight itself in only seconds. Spawn so created are less powerful that typical wights. Spawn are under the command of the wight that created them and remain enslaved until its death, at which point they become full-fledged and free-willed wights. They do not possess any of the abilities they had in life.

Frost Wights

Wights created in cold environments sometimes become pale undead with blue-white eyes and ice in their hair. Frost wights have immunity to cold and vulnerability to fire. Their slam attacks deal cold damage in addition to the normal effects. A creature touching a frost wight with natural weapons or unarmed strikes takes cold damage.
