Each method of manipulating magic has it's advantages and disadvantages. Each also has a unique way of viewing the world and the magic within it. Many Adepts will say that only their own way of viewing magic is valid, but the truth is that all four ways have their uses, and none is better than any of the others in an absolute sense.
Each element has associated with it a separate Plane of existence and various powerful spirits and otherplanar entities. These Planes can be visited by those Adepts who possess the knowledge and magical power, though they are very different from our world, and are often hostile. Alternatively, the entities who inhabit these planes can be summoned and controlled through the use of various talents.
The spells of the Elementalist deal with the creation and manipulation of the five elements and their aspects. Elementalists have many spells useful in combat, as well as the ability to create extraordinary items through the incorporation of True Elements into their structure. Elementalists as a whole are well-rounded, and an asset to any group of adventurers.
Illusions act directly on the mind. Using magic, an Illusionist builds an image, and then impresses that image onto the minds of his audience. With the power of magic and his own imagination, a skilled Illusionist can completely convince his audience that his creation is every bit as real as they are. Such creations can actually cause damage, as the believer's mind is convinced that the damage has occured.
Illusionist spells vary in power. Through the skilled use of illusion, an Illusionist can terrify even the most hardened opponents, or charm the most obstinate child. Illusionists often are outgoing, friendly individuals, even if they are prone to boasting.
