Custom spellmaking
Custom spells combine effects after the matching base spell is acquired, with up to eight effects per spell according to the guide.
How it works
The guide says a base spell containing an effect must be purchased before that effect can be used in a custom spell. Spellmaking services create custom spells, which can contain up to eight effects. On Touch and On Self effects can be combined without extra net Magicka cost compared with casting those effects separately, though the combined spell has a lower overall chance when its cost is high.
