Create a 3D digital illustration of a male fantasy character in a turn-based strategy game. The character is dressed in a Halloween-themed outfit with a tall, pointy black witch hat decorated with a subtle pumpkin design. He wears a sleeveless tunic in shades of orange and green, giving him a festive and mystical appearance. He holds a magical staff with a mystical, slightly curved top, but without any pumpkin decoration on the staff. The male character stands confidently on a checkered dungeon floor, surrounded by dark, atmospheric lighting, as if ready for a magical battle. Next to him, include a small, dark creature companion to enhance the sense of adventure and magic. Ensure the character has a cartoonish yet detailed style that is suitable for a fantasy game, with vibrant colors, crisp details, and a mischievous or determined expression
