I'm sure this has been answered, but I couldn't find it. I have spent days doing nothing but building my character's skill levels (and over all levels) in everything magick. I finally got all my levels to master(except restoration), and it is still costing more magicka that I've got to make spells. Master level illusion, and it is still not enough to bring the cost down to make a better paralyze spell. That's just an example. The same is true for destruction spells. How can it be done? I'm so sick of working so hard and getting no where.
What is the value of your Intelligence Attribute? Is this too, at 100? The higher your INT, the bigger magicka pool you have to play with.
When creating a spell at the altar, try using less damage over longer time, the spell cost will be reduced.
Touch spells cost less magicka to cast than target spells.
Last, if you create a lot of custom spells like I do, adding points to Luck helps out. NOTE: This adding of Luck, when your magic school levels are all at 100, only reduces the magicka cost of your
CUSTOM spells only, by about every four points of luck added.
Give an example.
