need help with scripting

ok so i'm making a weapon script. on equip it give you some special abilities but drains magicka at the same time, when you magicka hits 0, the special ability wears off.

I'm having trouble finding a script that detects the magicka level. soooo any help? is there like a list of commands that I can look at or sample mods?

if you're still confused, this is what I'm talking about

Ifmagickalevel=0
