Spawn of Shub-Niggurath (AC9, MV 6[land] 9[fly], HD4, SA immobilizing vapors & acid spray, SD infra- and ultra-vision, AL C): a grey amoeboid with no external features but exceptional vision, it continuously wafts paralytic vapors that are effective at melee range and require a save vs. paralysis at -3 to withstand.
This skulking fiend flaps down from starry skies to feed upon the helpless. It typically selects small children, the infirm, or the disabled for victims. It is a silent killer – the unfortunate is rapidly engulfed, the paralytic fumes ensuring that any struggle is stifled. Powerful digestive acids dissolve the body within an hour and the spawn then makes its escape. It has no standard attack (although its fumes are effective against melee attackers), but can spray a stream of digestive acid (2D damage) up to 30′ three times per day.
This beast’s ectoplasm can be distilled into several vials of a potent contact anesthetic, quite valuable if a sophisticated buyer can be found.
