Frankly, /SCH does more for Dark Magic than what gear we have available ever could. Downside, you don't actually have /DRK's spells with this aside from Drain and Aspir. While perhaps not as lulz as us and Shield skill/Mastery, Dark and Divine magic are two of our aspects that have been much slowly antiquated. Depending on future gear additions, my dark magic set will probably be some of the first gear phased out.
