Skyrim perks Augmented Frost, Augmented Fire, Augmented Shock. How are they made to change only one time of element spells? In creation kit, I cant find any settings to adjust magnitude of one time of Element spells... I am trying to make my own skyrim perk rework and i am working on destruction at the moment. Also i would like to make those perks work with runes and cloak magic.

I believe they use keywords, something along the lines of magical effect fire keyword/magical effect frost keyword/ or something similar to that.

EPMagic_SpellHasKeyword in the perk conditions. This is extremely useful for customizing which spells you want to be affected by the perk.
