If you're talking about things like Seducer 10% reduction, apparently its a proc type which runs a constant check on whether or not something cost magicka when it is cast which is when it applies. Racial, Class, and Skill line passives do show reduction as they are always active. I get a nice 11% cost reduction across the board on all abilities with Red Diamond combined with Restoring Spirit.
