He might have enhanced magical abilities. Since he has infinite time to practice and learn, his spells could be more powerful. Maybe he'd develop new forms of magic that normal wizards haven't thought of. Also, his immortality itself could be considered a power. He could endure any kind of physical or magical attack without dying, which gives him an edge in battles.
Well, his immortality could change the story in many ways. For example, he might be more reckless in dangerous situations because he can't die. He could also become a sort of mentor figure over time, having seen so much and having all the time in the world to gain knowledge. His immortality might also bring out the envy or fear of other characters, leading to new conflicts.
