For other uses, see Alteration.

Alteration is a skill in The Elder Scrolls II: Daggerfall and one of the six formal avenues of magical study. Alteration spells are those concerned with magic's ability to change the very structure and composition of objects, such as Dimunition or Shield. Buying, creating, and casting a Alteration spell is less expensive for mages skilled in this. Its governing attribute is Willpower.

It is a primary skill for Mages and Sorcerers, a major skill for Battlemages, Healers, and Spellswords, and a minor skill for Bards and Nightblades. The Mages Guild, Akatosh Chantry, and School of Julianos offer training.
