You gain 3 experience every time you cast an Illusion spell.
- The best spell for training is Starlight, it's the only novice spell you can cast on yourself and is quite cheap.
- Once you've completed the Recommendation quests for the Mages Guild, create a custom Starlight spell with the lowest magnitude. It will only take one or two magika points to cast so by the time you've cast the spell you should of regenerated the magicka anyway.
- Cast Starlight spells everywhere you go.
- Equip a weapon and hold block, and you'll cast spells quicker.
