A few days later, deep within the labyrinthine darkness of the 25th floor, a band of beleaguered adventurers faced their direst challenge yet. The cavern around them, lit only by the flickering glow of their torches, echoed with the sounds of battle.
They confronted a fearsome fourth-level monster known as the "Ghost Face Giant Ape" a towering beast over three meters tall, its body sheathed in shaggy, midnight-black hair. The creature's limbs were pillars of muscle, robust as the trunks of ancient trees, with calves and forearms as thick as oil barrels. Its visage was unsettlingly human-like, with a pronounced brow and a gnarled nose, the skin red and creased like that of a weathered elder. From beneath its snarling lips, yellowed fangs jutted out, adding a grotesque touch to its already formidable appearance.
