Ok, if I read Dread Witch correctly... technically I could use Fearful Empowerment on a Detect Magic that I cast on myself and then make permanent. Thus I would be perpetually subject to a fear effect, albeit just one that could make me shakened, and benefit from +1 CL or cast a free cantrip every turn, right? Or I could make a choker of Fear that constantly targets the wearer with the spell, and get +3 CL or a free 2nd spell every round...
Holy crap, Dread Witch is awesome.
