Disease (Ex): Demon fever [bite, Fortitude save (DC 18), incubation period 1 day; damage 1d6 temporary Constitution.] Each day thereafter, on a failed save, the creature must immediately succeed at another Fortitude save or suffer 1 point of permanent Constitution drain.

Spell-Like Abilities: At will - detect chaos, detect evil, detect good, detect law, detect magic, magic missile, polymorph self, ray of enfeeblement, and sleep. These abilities are as the spells cast by an 8th-level sorcerer (save DC 11 + spell level). A night hag can use etherealness at will as a 16th-level sorcerer so long as it possesses its heartstone (see below).

Dream Haunting (Su): Night hags can visit the dreams of chaotic or evil individuals by using a special periapt known as a heartstone to become ethereal, then hovering over the creature. Once the hag invades someone's dreams, it rides on the victim's back until dawn. The sleeper suffers from tormenting dreams and suffers 1 point of permanent Constitution drain upon awakening. A sleeper reduced to a Constitution score of 0 dies. Only another ethereal being can stop these nocturnal intrusions, by confronting and defeating the night hag.

Immunities (Ex): Night hags are immune to fire and cold, and to charm, sleep, and fear effects.

Heartstone (Su): All night hags carry this periapt, which instantly cures any disease contracted by the holder. In addition, a heartstone imparts a +2 resistance bonus to all saving throws. A night hag that loses this charm can no longer use etherealness until it can manufacture another (which takes one month). Good-aligned creatures can also benefit from the heartstone's powers, but the periapt shatters after ten uses and does not bestow etherealness.

Flaming Hooves (Su): A blow from a nightmare's hooves sets combustible materials alight.

Smoke (Su): During the excitement of battle, a nightmare often snorts and neighs with rage. This fills a 15-foot cone with a hot, sulfurous smoke that chokes and blinds opponents. Anyone in the cone must succeed at a Fortitude save (DC 16) or suffer a -2 morale penalty to all attack and damage rolls until 1d6 minutes after they leave the cone. The nightmare gains one-half concealment against creatures 5 feet away and total concealment against creatures 10 feet away. The smoke does not obscure the nightmare's vision at all. The nightmare can suppress the smoke as a free action.

Astral Projection and Etherealness (Su): These function just like the spells of the same names as cast by a 20th-level sorcerer.

Blinding Beauty (Su): This ability operates continuously, affecting all humanoids within 60 feet of the nymph. Those who look directly at the nymph must succeed at a Fortitude save (DC 15) or be blinded permanently as though by the blindness spell. The nymph can suppress or resume this ability as a free action.

Unearthly Beauty (Su): The nymph can evoke this ability once every 10 minutes. Those within 30 feet of the nymph who look directly at it must succeed at a Will save (DC 17) or die.

Spell-Like Abilities: Nymphs can use dimension door once per day as cast by a 7th-level sorcerer. They can also replicate druid spells as 7th-level casters (save DC 13+ spell level).

Poison (Ex): Bite, Fortitude save (DC 17); initial and secondary damage 1d8 temporary Constitution.

Spells: Water nagas cast spells as 7th-level sorcerers but never use fire spells.

Poison (Ex): Bite, Fortitude save (DC 18); initial and secondary damage 1d8 temporary Constitution.

Charming Gaze (Su): As charm person, 30 feet, Will save (DC 17).

Spells: Spirit nagas cast spells as 7th-level sorcerers, and can also cast cleric spells and spells from the domains of Chaos and Evil as arcane spells.

Detect Thoughts (Su): A dark naga can continuously detect thoughts as the spell cast by a 9th-level sorcerer (DC 15). This ability is always active.

Poison (Ex): Sting, Fortitude save (DC 16) or lapse into a nightmare-haunted sleep for 2d4 minutes.

Guarded Thoughts (Ex): Dark nagas are immune to any form of mind reading.

Charm Resistance (Ex): Dark nagas receive a +2 racial bonus to saving throws against all charm effects (not included in the statistics block).

Spells: Dark nagas cast spells as 7th-level sorcerers.

Poison (Ex): Bite, Fortitude save (DC 19); initial and secondary damage 2d8 temporary Constitution.

Spit (Ex): A guardian naga can spit its venom up to 30 feet as a standard action. The attack ignores armor and has no range increment. Opponents hit by this attack must attempt saves against the naga's poison, as above.

Spells: Guardian nagas cast spells as 9th-level sorcerers, and can also cast cleric spells and spells from the Good and Law domains as arcane spells.

Undead: Immune to mind-influencing effects, poison, sleep, paralysis, stunning, and disease. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.

Chill Aura (Su): All nightshades radiate a 60-foot-radius aura of utter cold. While this aura does not damage living things, it spoils any food and drink it touches. In addition, it ruins holy water and magic potions, oils, and ointments unless the items succeed at a Fortitude save (DC 22). Items that successfully save cannot be affected again by the same nightshade's aura for one day. This bone-numbing cold is so distinctive that anyone exposed to it once instantly recognizes it in the future, so it is difficult for a nightshade to surprise someone who has previously encountered such a beast.

Spell-Like Abilities: At will-cause disease, charm person, cloudkill, confusion, darkness, dispel magic, haste, hold person, and invisibility; once per night: finger of death. These abilities are as the spells cast by a sorcerer whose level equals the nightshade's HD total (save DC 14 + spell level).

Summon Undead (Su): A nightshade can summon undead creatures once every 4 hours: 2-5 shadows, 1-2 wraiths, 1 spectre, or 1 ghost. The undead arrive in 1d10 rounds and serve for 1 hour or until released.

Aversion to Daylight (Ex): Nightshades are creatures of utter darkness. While they loathe all light, if exposed to natural daylight (not merely a daylight spell), they suffer a -4 morale penalty to all attack rolls.

Cold Immunity (Ex): Nightshades suffer no damage from cold.

Resistances (Ex): Nightshades have acid, fire, and electricity resistance 50.

Spell Immunity (Su): Nightshades ignore the effects of spells and spell-like abilities of 6th level or lower, just as if the spellcaster had failed to overcome spell resistance.

Detect Magic (Su): A nightshade can continuously detect magic as the spell cast by a 20th-level sorcerer. It can suppress or resume this ability as a free action.

See Invisibility (Su): A nightshade can continuously see invisibility as the spell cast by a 20th-level sorcerer. It can suppress or resume this ability as a free action.

Telepathy (Su): Nightshades can communicate telepathically with any creature within 100 feet that has a language.

Damage Reduction (Su): All nightshades have damage reduction 25/+3.

Magic Drain (Su): A nightwing can weaken magic armor, weapons, and shields by making a successful touch attack. The target item must succeed at a Fortitude save (DC 20) or lose one "plus" (for example, a +2 sword becomes a +1 sword). An item that is completely drained becomes normal in all respects and loses any other powers (such as flame tongue) as well. Casting dispel evil upon the item reverses the effects of the magic drain, provided this occurs within a number of days after the attack equal to the caster's level.

Undead: Immune to mind-influencing effects, poison, sleep, paralysis, stunning, and disease. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.

Damage Reduction (Su): All nightshades have damage reduction 25/+3.

Crush Item (Su): A nightwalker can destroy any weapon or item of Large size or smaller (even magic ones, but not artifacts) by picking it up and crushing it between its hands. This is a standard action. The nightshade must make a successful disarm attack to grab an item held by an opponent.

Evil Gaze (Su): Curse, 30 feet, Will save (DC 24). Cursed opponents suffer a -4 morale penalty to all attack rolls, checks, and saving throws. Dispel evil or remove curse eliminates the effect.

Improved Grab (Ex): To use this ability, the nightcrawler must hit with its bite attack. If it gets a hold, it automatically deals bite damage and can try to swallow the opponent.

Swallow Whole (Ex): A nightcrawler can try to swallow a grabbed opponent of Huge or smaller size by making a successful grapple check. Once inside, the opponent takes 2d8+12 points of crushing damage plus 1d8 points of acid damage per round from the nightcrawler's gizzard, and is subject to the creature's energy drain. A swallowed creature can climb out of the gizzard with a successful grapple check. This returns it to the nightcrawler's maw, where another successful grapple check is needed to get free. A swallowed creature can also cut its way out by using claws or a Small or Tiny slashing weapon to deal 35 points of damage to the gizzard (AC 24). Once the creature exits, muscular action closes the hole; another swallowed opponent must cut its own way out. The nightcrawler's interior can hold two Huge, four Large, eight Medium-size, sixteen Small, or thirty-two Tiny or smaller opponents.

Energy Drain (Su): Living creatures inside a nightcrawler's gizzard receive one negative level each round. The Fortitude save to remove a negative level has a DC of 24.

Poison (Ex): Sting, Fortitude save (DC 22); initial and secondary damage 2d6 temporary Strength.

Tremorsense (Ex): A nightcrawler can automatically sense the location of anything within 60 feet that is in contact with the ground.
