The School of Illusion involves manipulating the mind and senses of the enemy. This skill makes it easier to cast spells like fear, charm, and invisibility.
Things are rarely as they seem in Tamriel, and casters who practice the deceptive art of Illusion prefer it that way. Illusion is an excellent talent for a caster who wishes to swindle a merchant, sneak around undetected, or drive a creature into a frenzy to escape.
