Explosion (Su): If a xag-az is reduced to 0 hit points, its body is instantaneously destroyed in an explosion of energy that deals 1d8+6 points of damage to everyone in a 20-foot-radius burst (Reflex save DC 16 half). The type of energy (acid, cold, electricity, fire, or sonic) is random (see Table below).

Psionics (Sp): At will -- detect psionics; 3/day -- dismiss ectoplasm, negate psionics. Manifester level 15th; save DC key ability modifier + power level. Attack/Defense Modes: At will -- ego whip/mental barrier.

Energy Lash (Su): A xag-az can make a ranged touch attack or hit with an incorporeal touch attack to deal an additional 2d8+6 points of energy damage to the target. A xag-az can control its energy enough to select the type of energy (acid, cold, electricity, fire, or sonic) for each attack. This power can be used up to five times per day.

Incorporeal Subtype: A xag-az can be harmed only by other incorporeal creatures, +1 or better magic weapons, spells, spell-like abilities, and supernatural abilities. The creature has a 50% chance to ignore any damage from a corporeal source, except for force effects or attacks made with ghost touch weapons. A xag-az can pass through solid objects, but not force effects, at will. Its attacks ignore natural armor, armor, and shields, but deflection bonuses and force effects work normally against them. A xag-az always moves silently and cannot be heard with Listen checks if it doesn't wish to be.

Outsider Traits: Xag-az possess darkvision (60-foot range), and they cannot be raised or resurrected (though a wish or miracle spell can restore life).

Plane Shift (Su): If a xeg-yi or xag-ya makes contact with a xag-az, the xag-az is immediately shifted to a random location on the Astral Plane, and the xeg-yi or xag-ya is shifted to a random location on a random plane. If a xag-ya or xeg-yi perceives a xag-az, they flee if possible. The xag-az generally ignores both the xag-ya and xeg-yi, unless they happen to be guarding something the xag-az is curious about.


Incorporeal Subtype

Some creatures are incorporeal by nature, while others (such as those that become ghosts) can acquire the incorporeal subtype. An incorporeal creature has no physical body. It can be harmed only by other incorporeal creatures, magic weapons or creatures that strike as magic weapons, and spells, spell-like abilities, or supernatural abilities. It has immunity to all nonmagical attack forms. Even when hit by spells, including touch spells or magic weapons, it has a 50% chance to ignore any damage from a corporeal source (except for positive energy, negative energy, force effects such as magic missile, or attacks made with ghost touch weapons). Non-damaging spell attacks affect incorporeal creatures normally unless they require corporeal targets to function (such as the spell implosion) or they create a corporeal effect that incorporeal creatures would normally ignore (such as a web or wall of stone spell). Although it is not a magical attack, a hit with holy water has a 50% chance of affecting an incorporeal undead creature.

An incorporeal creature's natural weapons affect both in incorporeal and corporeal targets, and pass through (ignore) corporeal natural armor, armor, and shields, although deflection bonuses and force effects (such as mage armor) work normally against it. Attacks made by an incorporeal creature with a nonmagical melee weapon have no effect on corporeal targets, and any melee attack an incorporeal creature makes with a magic weapon against a corporeal target has a 50% miss chance except for attacks it makes with a ghost touch weapon, which are made normally (no miss chance).

Any equipment worn or carried by an incorporeal creature is also incorporeal as long as it remains in the creature's possession. An object that the creature relinquishes loses its incorporeal quality (and the creature loses the ability to manipulate the object). If an incorporeal creature uses a thrown weapon or a ranged weapon, the projectile becomes corporeal as soon as it is fired and can affect a corporeal target normally (no miss chance). Magic items possessed by an incorporeal creature work normally with respect to their effects on the creature or another target. Similarly, spells cast by an incorporeal creature affect corporeal creatures normally.

An incorporeal creature has no natural armor bonus but has a deflection bonus equal to its Charisma bonus (always at least +1, even if the creature's Charisma score does not normally provide a bonus).

An incorporeal creature can enter or pass through solid object but must remain adjacent to the object's exterior, and so cannot pass entirely through an object whose space is larger than its own. It can sense the presence of creatures or objects a square adjacent to its current location, but enemies have total concealment from an incorporeal creature that is inside an object. In order to see clearly and attack normally, a incorporeal creature must emerge. An incorporeal creature inside an object has total cover, but when it attacks a creature outside the object it only has cover, so a creature outside with a readied action could strike at it as it attacks. An incorporeal creature cannot pass through a force effect.

Incorporeal creatures pass through and operate in water as easily as they do in air. Incorporeal creatures cannot fall or take falling damage. Incorporeal creature cannot make trip or grapple attacks against corporeal creatures, nor can they be tripped or grappled by such creatures. In fact, they cannot take any physical action that would move or manipulate a corporeal being or its equipment, nor are they subject to such actions. Incorporeal creatures have no weight and do not set off traps that are triggered by weight.

An incorporeal creature moves silently and cannot be heard with Listen checks if it doesn't wish to be. It has no Strength score, so its Dexterity modifier applies to both its melee attacks and its ranged attacks. Non-visual senses, such as scent and blindsight, are either ineffective or only partly effective with regard to incorporeal creatures. Incorporeal creatures have an innate sense of direction and can move at full speed even when they cannot see.
