Im sure this has been covered somewhere, but I couldnt find anything. With spells like Dust Cloak and Heart of Fury (and many others since Prophecies) that say "for X seconds, your weapon deals [elemental] damage" (it's not always elemental, i know, but for the sake of brevity, it'll do). Does this not mean you do extra damage in addition to your regular damage? Is it that the damage your weapon does is considered part of that school of magic for the duration of the enchantment? Just trying to get a grasp on the advantage of these types of enchantments.
