That night, Wolfe focused on learning the rest of the essentials of array formation. He needed the knowledge of how to link multiple spells together so that he could move on with his knowledge of utility spells, which would make his everyday life easier.
The principles were easier than he had expected. According to the Inheritance, the key to making Arrays that worked correctly was in the layering. The inscribed array should be the basic spells that were needed to achieve the effect, and then you would create an activation layer over the top with all the modifications to impose your will and intent.
That was why the witches couldn't make most Arrays work. They could activate all the spells individually, but Elemental Magic of that sort wasn't innate to them, so they couldn't activate the uninscribed upper layer.
