Etheral is a problem in a few of my books, my beastmasters specifically, but i run priest a lot and that's got ethereal built in. Strangely enough lightning bolt is ending up in a lot my books lately. Its one cheaper than force hammer and the stun chance really does a lot of work in many games.
Im very excited about vorpal blade being available now! This will make taking out deathlock and other crippling conjurations much much easier.
