Note the double space in spell reqs.

Gauthus says, "Discovered in an ancient cave by Dwarven Warrior Mages, the Aegis of Granite spell is one of the rarefied patterns known as Elemental Transformations, carrying with it the limitations of such magic. By invoking a metaphysical manifestation of Earth energy in your body, it will augment your strength, stamina, and shield usage. Before you can learn this spell, you must know and Aether Cloak. It will also cost three spell slots. It cannot be targeted."

Side Note, any way to get a updated copy over to test?
