Construct
A construct is an animated object or artificially constructed creature.
Traits
A construct possesses the following traits (unless otherwise noted in a creature’s entry).
- No Constitution score.
- Low-light vision.
- Darkvision out to 60 feet.
- Immunity to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects).
- Immunity to poison, sleep effects, paralysis, stunning, disease, death effects, and necromancy effects.
- Cannot heal damage on their own, but often can be repaired by exposing them to a certain kind of effect (see the creature’s description for details) or through the use of the Craft Construct feat. A construct with the fast healing special quality still benefits from that quality.
- Not subject to critical hits, nonlethal damage, ability damage, ability drain, fatigue, exhaustion, or energy drain.
- Immunity to any effect that requires a Fortitude save (unless the effect also works on objects, or is harmless).
- Not at risk of death from massive damage. Immediately destroyed when reduced to 0 hit points or less.
- Since it was never alive, a construct cannot be raised or resurrected.
- Because its body is a mass of unliving matter, a construct is hard to destroy. It gains bonus hit points based on size, as shown on the table.
- Proficient with its natural weapons only, unless generally humanoid in form, in which case proficient with any weapon mentioned in its entry.
- Proficient with no armor.
- Constructs do not eat, sleep, or breathe.
Incorporeal
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 is immune to all non-magical attack forms. Even when hit by 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). Although it is not a magical attack, holy water can affect incorporeal undead, but a hit with holy water has a 50% chance of not affecting an incorporeal creature.
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 objects, 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 within a square adjacent to its current location, but enemies have total concealment (50% miss chance) from an incorporeal creature that is inside an object. In order to see farther from the object it is in and attack normally, the 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.
An incorporeal creature’s attacks pass through (ignore) natural armor, armor, and shields, although deflection bonuses and force effects (such as mage armor) work normally against it. Incorporeal creatures pass through and operate in water as easily as they do in air. Incorporeal creatures cannot fall or take falling damage. Incorporeal creatures cannot make trip or grapple attacks, nor can they be tripped or grappled. In fact, they cannot take any physical action that would move or manipulate an opponent 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.
