I'm having some trouble with the angels' Economy incept. It's clear that when a power affects the angel, the power's activator must pay (rank) energy.
But what about Mage Sight? If a mage uses Mage Sight in the vicinity of the angel and just looks at it does he also have to pay (rank) mana for that?
And in addition to that, as the two are linked, is Scrutinize. Does each roll invoke the cost? Or is it only invoked once?
Note that this question is specifically about angels who are in cover and thus material.
