Monster Manual III
Prismatic Body (Su): A prismatic golem's body is comprised of scintillating colors. Creatures with 8 HD or fewer within 20 feet of a prismatic golem are blinded for 2d4 rounds by the flashing colors (no save). Any creature that touches a prismatic golem is treated as though the golem had hit it with its prismatic touch attack. A prismatic golem can be seen from miles away, and provides illumination as a daylight spell at all times.
Prismatic Touch (Su): A prismatic golem attacks with luminous tendrils that extend from its body. A tendril's color is determined randomly, since the golem lacks the intelligence to choose colors on its own. The effect of the touch attack is based on the tendril's color, as shown on the following table. The save DCs are Charisma-based.
| d8 | Color | Effect |
| 1 | Red | 5d6 points of fire damage |
| 2 | Orange | 5d6 points of acid damage |
| 3 | Yellow | 5d6 points of electricity damage |
| 4 | Green | 10d6 points of damage (as disintegrate spell; Fortitude DC 20 half) |
| 5 | Blue | 5d6 points of cold damage |
| 6 | Indigo | Insanity (as spell; Will DC 20 negates) |
| 7 | Violet | 5d6 points of sonic damage |
| 8 | White | 5d6 points of force damage |
Immunity to Magic (Ex): A prismatic golem is immune to any spell or spell-like ability that allows spell resistance. In addition, some spells and effects function differently against the creature, as noted here.
A prismatic spray heals the golem of 3d8 points of damage +1 point per caster level (maximum 3d8+15). Contact with a prismatic wall or prismatic sphere also heals the golem in this way, and ends the spell's effect.
Moral Code: Though unintelligent, a prismatic golem is imprinted with the moral code of its creator. It will cease to function on its controller's behalf if given any instructions that conflict with that moral code, regardless of whether the creator's ethics change.
When commanded, a prismatic golem moves up to a foe and strikes him with its tendrils. The golem is disarmingly fast and elusive, so it never hesitates to distance itself from those who can hurt it.
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.
Good Subtype
A subtype usually applied only to outsiders native to the good-aligned Outer Planes. Most creatures that have this subtype also have good 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 good alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the good subtype overcomes damage reduction as if its natural weapons and any weapons it wields were good-aligned (see Damage Reduction).
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.
