Aura of Servile Avians (Su): All evil-aligned creatures with a natural fly speed feel a strange bond of attraction to Pazuzu. Before such a creature takes any hostile action against Pazuzu, it must attempt a DC 34 Will save. Failure indicates that the creature's attack fails and its action is wasted. This aura extends to a radius of 120 feet. The save DC is Charisma-based.

Breath Weapons (Su): Pazuzu has two breath weapons. The first can be used to create six swarms of locusts (all of which must be created so that each swarm is adjacent to at least one other swarm, and at least one square must be adjacent to Pazuzu). He can create these swarms so that they share the area of other creatures. The locusts attack any creatures occupying the squares and can pursue creatures that flee.

Pazuzu's second breath weapon is a 60-foot cone of poisonous acidic vapor. All creatures caught in this area take 18d6 points of acid damage (DC 35 Reflex halves) and must also succeed on a DC 35 Fortitude save or take 2d4 points of Strength damage from the poison. A minute later, a second DC 35 Fortitude save is required, this time to avoid the secondary damage of 2d4 points of Constitution damage. The save DCs are Constitution-based.

Regardless of which breath weapon he uses, Pazuzu can only use this special attack once every 1d4 rounds.

Summon Avians (Sp): Once per day, Pazuzu can automatically summon 2d6 elder arrowhawks, 1d6 harpy archers, or 1d6 fiendish rocs. This ability functions as a 9th-level spell (CL 20th).

Summon Tanar'ri (Sp): Once per day, Pazuzu can automatically summon 2d4 succubi, 1d4+2 vrocks, or 1 balor. This ability is the equivalent of a 9th-level spell (CL 20th).

Temptation (Su): If a creature utters the name "Pazuzu" three times in succession, an unholy link between the speaker and Pazuzu is immediately established. For one minute, Pazuzu can use detect good, detect law, detect thoughts (DC 22), and tongues to examine the speaker, despite any distance (physical or planar) that might separate them. He always uses Sense Motive to try to determine whether the one who calls him is trying to entrap him.

If he wishes and is able, Pazuzu can use plane shift and greater teleport to travel to the speaker's location with precise accuracy, as long as he does so before the minute is up. Once he arrives, Pazuzu asks the speaker why he called upon the Prince of the Lower Aerial Kingdoms. Pazuzu almost always agrees to provide aid, but if he does, the caller's alignment shifts one step closer to chaotic. If the caller's alignment is already chaotic, it instead shifts one step closer to evil. These shifts in alignment are considered voluntary. Pazuzu never provides aid to chaotic evil creatures and often punishes them for calling upon his aid rather than using the tools he has likely already granted the creature in question.

Pazuzu particularly enjoys corrupting paladins and takes pains to ensure that the first time he helps a paladin, no evil comes as a result of his assistance, hoping to encourage the paladin to call on him again. Aid granted by Pazuzu is typically granted in the manner easiest for the demon prince to manifest, often in the form of his wish spell-like ability.

Chaotic Subtype

A subtype usually applied only to outsiders native to the chaotic-aligned Outer Planes. Most creatures that have this subtype also have chaotic alignments; however, if their alignments change they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has a chaotic alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the chaotic subtype overcomes damage reduction as if its natural weapons and any weapons it wields were chaotic-aligned (see Damage Reduction).

Evil Subtype

A subtype usually applied only to outsiders native to the evil-aligned Outer Planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields were evil-aligned (see Damage Reduction).

Extraplanar Subtype

A subtype applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This book assumes that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures.

Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane; the transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.

Obyrith Subtype

The strange and horrific Obyriths are primeval demons from eons past. They wrought chaos and evil upon the multiverse before the advent of intelligent life on the Material Plane. Their forms are hideous to behold, rarely if ever incorporating elements possessed by mortal creatures. Obyriths dwell only in the most remote corners of the Abyss. Their kind has been in decline since the rise of the tanar'ri in the Abyss, although a few tenacious examples continue to make their presence known on key layers.

Traits: An obyrith has the following traits (unless otherwise noted in a creature's entry).
