Does this perk affect class abilities for sorceror tree, or just those abilities in the destruction staff line?
What about light/heavy staff attacks?

"While you have a destruction staff equipped:
- Restore magicka when killing an enemy with a destruction spell"

It should be worded
"While you have a destruction staff equipped:
- Restore magicka when killing an enemy with a destruction STAFF spell"
