Under the science of Magic, spells utilize Magicka to manipulate reality to the whims of the Mage. Six spell-types exist in The Elder Scrolls IV: Oblivion, most of which are governed by the Intelligence and Willpower attributes. Illusion employs Personality, and is the main exception to this rule. While classes such as Battlemage and Healer specialize in spell-casting, all races and classes can cast some spells. A minor Restore health and a minor Fireball spell are learned by each race at the game's beginning.
