Description of the eight schools of magic from the D&D supplement "Complete Mage", for those who are curious.
Abjuration: By it's nature, an abjuration spell interferes with something else. Whether it blocks, banishes, protects, or rescues, an abjuration spell is dedicated to preventing or ending some other event or effect.
Conjuration: A conjuration spell creates or summons a real object or creature. The effect could appear in the spellcaster's hand, arrive from another plane of existence, or take shape in front of her.
Divination: A divination spell detects and reveals veiled information. The effect could disclose hidden traps, expose well-told lies, or foil enemy plans.
Enchantment: Enchantment spells focus on tricking the mind. They effectively manipulate emotions, perceptions, and even thoughts penetrating the most vulnerable parts of a creature's being.
Evocation: An evocation spell creates an effect out of thin air. The effect could blind its targets with searing light, immolate them with explosive fire, or shock them with electrical current. In Shadows & Light, Azshara is said to be the creator of most evocation spells.
Illusion: An illusion spell creates a false impression that targets the senses. The effect could hide your presence, summon a target's greatest fear, or manifest a visage limited only by your creativity.
Necromancy: Necromancy spells hold dominion over life and death. Their effects can drain the stamina out of an opponent's body, exert control over the undead, or instill paralyzing fear in a creature's mind.
Transmutation: A transmutation spell modifies energy and matter. The effect could alter a creature's shape, boost mental or physical qualities, or change the way something interacts with the world.--Austin P (talk) 13:45, 20 May 2008 (UTC)
