The information is wrong. I did not see any ability or entry point indicating a way to add regen magicka. Before I even suggested that, I thought about the idea of having to add this ability to all novice level spells, via magic effects(that'd take a lot of time).
Yeah. I'm exploring doing it through magic effects right now but it's giving me trouble. I'm not trying to make every novice level spell free, just the novice level destruction spells. It's something I'm willing to put the time into. That having been said, so far I've managed to get a flames spell to drain magicka from targets, which is essentially what I want it to do, but no matter what I do I can't seem to remove all of the animations involved in the drain magicka effect. When the spell is successfully draining magicka from a target the screen goes dark blue which makes it very difficult to see. Ideally I'd like to remove the dark blue hue but I set all of the animation options to "none" and it doesn't seem to work.
EDIT: I've managed to get it to work. It was just a matter of removing a script associated with the magic effect.
