Spell classes are categories of magical spells from a variety of schools that all serve a similar function, usually tailored to a specific outcome. Each class has a counter class which represents its conceptual opposite, for example Banishment is the counter class to Summoning and vice versa.

Counter class: Summoning

Spells in the Banishment class are concerned with the removal of entities and objects, whether from the caster's immediate location or even from the current plane of existence. They are conceptually opposite to the Summoning class.

Counter class: Translocation

Spells in the Binding class are concerned with stasis, immobility and the application of enchantments. They are conceptually opposite to the Translocation class.

Counter class: Destruction

Spells in the Creation class are concerned with the conjuration of new items and effects through magical means as well as restoring the damaged and disintegrated to their original forms. They are conceptually opposite to the Destruction class.

Counter class: Creation

Counter class: Binding

Spells in the Translocation class are concerned with movement, mobility and teleportation. They are conceptually opposite to the Binding class.

Counter class: Preservation

The circle of spell classes is a visual representation of the twelve classes and their conceptual alignments in relation to one another. While the proximity of the spell classes to their neighbours is designed to be as closely linked to one another as possible, this is purely conceptual and has no practical impact.

If for any reason the image above is not visible then the table below provides a similar visual representation of the same concept:
