This large Echinoderm mutation achieves sentience without a brain and amazing agility without a muscle structure. It is one of the few vampires capable of reproduction without a living host, as any portion severed from its body will slowly develop into a complete creature. Like a normal starfish, the pentasite regurgitates its stomach over prey, but no longer uses the organ in digestion. Rather, the stomach is utilized only as a sticky net to constrict prey and drag it towards the blood-sucking teeth.
