A soft humming sound gradually grows louder as a near-invisible form approaches. The air itself seems to ripple in its assage, distorting the view of the creature. The sounds of a thousand screams cry out as the creature moves.

A sonic construct is around 5 feet tall and has negligible weight (although it can exert pressure as if it weighed 40 pounds). Appearing as, essentially, a persistent sonic effect in the rough shape of a humanoid, they give off a perpetual hum easily heard by any within 10 feet. The volume of this hum increases marginally while moving, and dramatically while in combat, approaching a battle cry. Some sarcastic kineticists call these constructs “walking war cries,” although the name has yet to gain widespread use.


A sonic construct does nothing without explicit orders from its creator. It follows instructions literally and is incapable of any strategy or tactics. Sonic constructs don’t use weapons, even if ordered to, but always lash out with sonic arcs. A sonic construct’s creator can command it if the sonic construct is within 60 feet and can see and hear its creator. If un-commanded, a sonic construct usually follows its last instruction to the best of its ability, though if attacked it returns the attack. Its creator can give a sonic construct a simple command to govern its actions in his or her absence.

Shattering Scream (Su): A sonic construct uses the sonic energy of its form by emitting a devastating wail at its enemies. This wail is a 15’ cone that causes 3d4 points of sonic damage (Reflex half, DC 15). A shattering scream ignores the hardness of objects, and, if the construct focuses it on a single object, emulate a shatter spell. After making a shattering scream of either type, a sonic construct must wait one round before being able to do so again.

Sonic Form (Ex): A sonic construct, being pure sound, cannot mask its presence easily. Unlike other incorporeal creatures, it does not always move silently, instead taking a -4 racial penalty on Move Silently checks. Normal hearing distance is doubled for those making Listen checks near the sonic construct. Additionally, its natural attacks deal sonic damage instead of bludgeoning, and if used to attack an object ignore that object’s hardness. However, due to their imprecise nature, these natural attacks can no longer deal critical hits. Finally, it is immune to sonic damage and is in fact repaired by sonic energy: if it is subject to a magical or psionic attack which deals sonic damage, it recovers one hit point per die of damage the effect would have otherwise dealt. Its incorporeal miss chance does not apply against psionic or magical sonic attacks.

Construct Traits: A sonic construct has immunity to poison, sleep effects, paralysis, stunning, disease, death effects, necromancy effects, mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects), and any effect that requires a Fortitude save unless it also works on objects or is harmless. It is not subject to critical hits, non-lethal damage, ability damage, ability drain, fatigue, exhaustion, or energy drain. It cannot heal damage, but it can be repaired.

Incorporeal Traits: A sonic construct is harmed only by other incorporeal creatures, magic weapons, powers, spells, spell-like abilities, and supernatural abilities. It has a 50% chance to ignore any damage from a corporeal source, except for force effects or attacks made with ghost touch weapons. It 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. Sonic constructs have no Strength score, but are not silent as normal incorporeal creatures are.


A sonic construct’s body is constructed in an unusual fashion: a crystalline latticework is assembled, and then charged with psychokinetic energy during construction. The resulting resonance shatters the framework upon completion, but creates a sonic construct. The latticework requires 1000 gp in raw crystal and a DC 20 Craft (gemcutting) check to assemble.
