A more demented revival of an once extinct krasis. Through careful cultivations of biomantic magic, the species was brought back and gradually reintroduced to Simic Zonots and biomes, primarily for the sake of studying how a cytoplasm-based creature can survive without said cytoplasm in its system. Suffice to say, they've been a terrible success.
Large and horrid, they prey upon whatever they can web up and drain of their fluids, ranging from various Gruul monsters to even a few other krasis if given the chance. Webbing prey up with ooze-like webs, nearly impossible to escape, these monsters make for fierce guardians to Holdfasts, and intruders rarely get time to even realize they're dead before the fangs come.
