A colossal fantasy creature, a fusion between a giant spider and a massive octopus eight towering legs with a chitinous, armored texture, ending in claw-like tips, supporting a bulbous body covered in a mix of slick, mottled skin and hard carapace plates. Its central mass undulates like an octopus, with pulsating patterns glowing faintly across its surface. Long, serpentine tentacles emerge from beneath its body, twisting unnaturally with suction cups and barbed ends. The creature's head is a blend of arachnid eyes and cephalopod intelligence, with rows of glistening eyes and a central, beak-like mouth. It lurks in an ancient, mist-covered cavern, illuminated by bioluminescent fungi and eerie magical runes. fantasy DnD monster ultra-detailed creature design cinematic lighting 4k resolution atmospheric, high fantasy setting dark, mysterious, and epic tone concept art trending on ArtStation sharp focus dramatic shadows fantasy horror vibe --ar 3:4 --v 7
