A terrifying undead spider monster with glowing green mist on its back and many eyes, lurking in a dark, misty dungeon corridor.

"A terrifying undead spider, medium-sized, its body a grotesque fusion of skeletal remains and blackened chitin armor. Patches of sinew stretch across its joints, and faint necrotic green mist seeps from cracks in its exoskeleton. Red and green glowing runes crawl like veins across its back, pulsing with dark magic. Dozens of multifaceted eyes gleam with malevolent intelligence, reflecting dim dungeon torchlight. Its fangs glisten with necrotic venom, dripping onto the cracked stone floor. Thin, tattered webs hang from its legs, clinging to the walls and ceiling. The creature skitters silently, a predatory shadow in a dark, misty dungeon corridor, evoking fear and dread. Ultra-detailed, dark fantasy, cinematic lighting, hyper-realistic textures, eerie atmosphere." See more
