The ability to make custom spells is important to any player using a magically inclined character. Up to eight effects can be combined into a single, potent spell; spells can be tweaked to provide maximum effect for minimal cost.
 Making Custom Spells
On the left side of the Spellmaking window you are presented with a list of all spell effects you have collected so far, which can be used to create the custom spell. Select an effect you wish to add, and a new screen pops up where you can set the range (self, touch, or target), minimum and maximum magnitudes, duration, and area of effect. These parameters determine the magicka cost of the spell, the chance of successfully casting the spell, and the gold cost of making it. Once you have finished setting the effect's parameters, you may then add additional effects (up to eight) if you wish. Finally, name the spell and then purchase it. Spell making is not available for vampires.
These NPCs will allow any character to create what spell they desire, but at a price.
- Multiple-effect spells will belong to the school of the effect that you have the lowest chance of successfully casting. For example, if you create a spell with Paralyze (Illusion school) and Damage Health (Destruction school) effects, and your chance of casting the Paralyze portion of the spell is lower than your chance of casting the Damage Health portion of the spell, the created spell will be tagged as an Illusion spell. If your Illusion skill increases to the extent that your chance of casting the Paralyze portion of the spell becomes higher than your chance of casting the Damage Health portion, the spell will be re-tagged as a Destruction spell.
- The chance to cast a spell is calculated with this formula:
([Luck / 8]+[Willpower / 4]+[Spell Skill * 2.5]-[Magic Cost * 1.25])*(0.6 + [0.4 * Current Fatigue / Max Fatigue])
