A construct is an artificial creature empowered by a force other than necromancy. Constructs are often mindless; they are immune to bleed damage, death effects, disease, healing, necromancy, nonlethal attacks, poison, and the doomed, drained, fatigued, paralyzed, sickened, and unconscious conditions; and they may have Hardness based on the materials used to construct their bodies.
