I do hope the battle evolves in stages instead of just picking one place on the battlefield and staying there hitting him 'til he's dead. I'd like to see him make use of his agility with a lot of special highly animated attacks, e.g. ariel AoE meteor/fireball attacks, carving runes on the ground to get the hell away from before they explode, or a fiery 360 degree long range flamethrower attack with the only safe spot being directly underneath him. Anything like this that makes us move around for optimal positioning at all times during the battle would be nice.
