Help a beginner with scripting

[AndreAIXIDOR]

Hi everybody, this is the first time I write on the forum (and the first "serious" mod I try to create),

I have 3 question,

first: I have a spell, aimed, I want the game add a magic effect to the caster every time the spell is casted (the magic effect is blank, it's only to prevent you from casting the spell); I try the onspellcast event but it doesn't work.

second: there is a way to reduce the stamina using for sprinting?

third: a way to increase the health regeneration proportionally of your missing health

Thanks to anyone answer me.

Not sure about the rest, but this mod here has edited sprinting to take less stamina so you can take a look at it and see how it works.
