If you missed it, Sean Punch added a new spell to the DFRPG:
It's an anti-evil spell that's available to wizards, clerics, and druids alike.
I'd probably add some negative prereqs - you can't be Excommunicated, you can't generally be evil (a combo of traits and actions, not a specific list of traits). But otherwise, this seems pretty good. It's definitely going on the cleric list - clerics of the Good God causing evil beings to take damage and flee is very in-setting for Felltower. I'd just need to say the Good God started to add it.
Druids and wizards - not yet. But it's a nice spell.
