This creature gives off light with the approximate brightness of a candle, and appears to be a shimmering cloud of filaments, tendrils, and whips of eerie mist. The form of the thing continuously roils and billows like a cloud, and it is eerily silent.

Once every 2 rounds as a standard action, an ectoplasm can release a 20-foot cone of ectoplasmic goo at its foes. Affected opponents must succeed on a DC 17 Fortitude save or be affected as if by a sleep spell (caster level 7th). A successful save renders a creature immune to that ectoplasm’s breath weapon for 24 hours. The save DC is Constitution-based.
An ectoplasm continually gives off light with the approximate brightness of a candle. It cannot consciously extinguish this light. When an ectoplasm is killed, this light fades to darkness.
An ectoplasm dwells on the Ethereal Plane and as an ethereal creature, it cannot affect or be affected by anything in the material world. When an ectoplasm manifests, it partly enters the Material Plane and becomes visible but incorporeal. A manifested ectoplasm can be harmed only by other incorporeal creatures, magic weapons, or spells, with a 50% chance to ignore any damage from a corporeal source. A manifested ectoplasm can pass through solid objects at will, and its own attacks pass through armor. A manifested ectoplasm always moves silently.
The touch of an ectoplasm deals 1d8 points of Strength damage to living opponents.
Many encounters with glowing, ghostly spheres can be attributed to ectoplasms rather than restless spirits. An ectoplasm, sometimes called a ghost ooze, is a faintly glowing orb of immaterial substance that lurks in catacombs and cemeteries. Although incorrectly assumed by most to be some form of incorporeal undead, ectoplasms are quite alive. Ectoplasms dwell in places of the dead because they consume dead flesh, slowly dissolving decaying bones and skin and absorbing the nutrients directly. The strange irony of the ectoplasm is that a cemetery ‘haunted’ by these creatures is almost certain to be free of any corporeal undead; the ectoplasm makes a meal of them as soon as it discovers them.
Although its primary diet consists of the dead, an ectoplasm is also a threat to the living. An ectoplasm attacks anything within the range of its senses that disturbs it. An ectoplasm that encounters a living opponent attacks for a few rounds before attempting to escape—it senses that it can get no sustenance from the opponent. If it finds an undead opponent, an ectoplasm continues to attack until it or the opponent has been destroyed.
