Incorporial Form would be a good addition, your entire body just goes transparent and you can bend reality to a certain degree altering the games perspective allowing certain parts of the countryside to literally absorb enemies. A spell which alters the entire surroundings would be good, sort of an advancement of the incorporial form thing with a mix of divine fury and infernal wrath- depending directly on your alignment, it morphs the entire landscape into either a hell or heaven dimension giving you strength and speed advantages over the enemy.
