Create a 3D digital illustration of a fantasy character in a turn-based strategy game. The character is dressed in a Halloween-themed outfit with a tall, pointy witch hat decorated with a pumpkin design and wears a sleeveless tunic in shades of orange and green. They hold a magical staff with a mystical, slightly curved top. The character stands confidently on a checkered dungeon floor, surrounded by dark, atmospheric lighting, as if ready for a magical battle. Add a small, dark creature companion next to the character 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 and crisp details.
