Triggered by Kingslakes post about gaining hitpoints, I've decided to start investigating the casting cost for spells.

As most of you know, the cost for a particular spell goes down as you increase in skill in the associated magic school. The question however is how much?

See post below.

Hello,

Instead of doing more experiments myelf, I found a wiki that lists the formulas I was looking for. Here is the link.

http://www.uesp.net/wiki/Oblivion:Spell_Making


Short summary:

Casting cost = Base cost * (1.4 - (skill * 0.012))

A note on the skill, apparantly luck modifies the skill before being used in the above calculation. But the skill is still capped to 100.

The formula for luck is:

Modified skill = Base skill + (0,4 * (Luck - 50))

So the maximum skill modifier for max luck is +20.


So using these formulas you can calculate if and at what level/cost you will be able to cast those expensive spells!

All the credit goes to the wiki contributors of course.
