The demon dog was indeed a formidable creature, closer to a true demon than any William had faced before. Its physique was robust, rivaling that of a half-wolf, and it wielded dark magic with ease. William could feel the oppressive weight of its power, sensing the various abilities it possessed: dark energy balls that could explode on impact, flames that could incinerate anything in their path, and a shroud of black fog that could obscure its movements.
As William prepared for battle, he realized the demon dog's combat style was as diverse as its abilities. In the tight confines of the mine, it would charge at him like a raging bull, using its incredible strength to keep William on the defensive. There would be no room for error or escape.
