About restoration school:

I'm trying to make a magic effect of shadows. like a power from hell! lol visual effects are ok. but i'm having some trouble with an concept:

if i'm using a source of evil power, the light/good powers should not affect me. so, what I simply want is that when I activate this evil magic effect, all the restoration spells cannot affect me or be used by me. I could not heal myself, be healed by others, cure others or even use spells of these school. if possible only potions would work to restore my health.

I imagine that I should use a perk for doing it, but I dont know exactly how to set the perk for it block restoration school in this complex way
