You probably won't find a good spell in Spell Casters. Anyone can add spells to that site and a lot of newbs do. Allot of newbs will also join that coven and pretend to be all knowing. As you could probably guess from those last two sentences, the Spell Casters coven doesn't get a lot of respect on this site.
There are spells you could cast, but I think a meditation would probably be more effective. Do you have any experience with meditation?
