Tickler
a.k.a. Osseopede, Calcipede, Aranach, and Spidoss.
These composites collect as an assortment of bones and osseous matter, sporting ghastly, makeshift legs that lend them an arachnid appearance. The skeletal union of several different creatures and devoid of flesh, they are the inverse of Blotches. They have a symbiotic relationship with them, each feeding on different parts of their victims, though Tickler sightings are by far more common.
Like their abominable kin they lack intellect; perhaps a mercy considering their disposition. Depending on their configuration, these creatures will adopt their own gaits, characteristics, and preferred prey. Affectionately dubbed Ticklers, these malignant Undead prefer to stab, tear and render their prey apart to reach the bones inside. Their destruction is challenging, and best accomplished by dismemberment, pulverization, and preferably followed by immolation. The sound of their joints clicking as they shamble along is one of the few mercies offered by these Undead.
The Undead are big fans of recycling.
