Illusion is one of the six skills that fall under The Mage play-style. Targeted Illusion spells include Calm, Frenzy, Fear, or Courage and spells cast on one's self such as Muffle or Invisibility. Casting Illusion spells raise the corresponding skill. Casting Illusion spells consumes Magicka. The effectiveness of Illusion spells depends on the caster's skill and the foe's resistance to the spells or spells in general. Some beings are entirely immune to Illusion magic. Only one race begins the game with an Illusion spell; an Altmer Dragonborn, with the rage-inducing spell Fury. Those of meri blood excel at Illusion and begin the game with increased ranks in the skill. Altmer begin with 25, while Bretons and Dunmeri individuals begin with 20.
