Beguilers are a very awesome class. If the bad guys always get lucky rolls, I suspect likewise that your DM is a ****. But depending on their level, beguilers have a number of alternatives like illusions (minor image and such), buffing the party, Shadow Evocation, and taking extra spells via the Arcane Disciple feat.
I thought that they looked awesome as well. ^^ Hm... doesnt shadow evocation requires will save as well?? I tried throwing an ice spell (dont remeber the name) at a red dragon... and he got a will save. Only took 20%of the original damage.

But still, I want to play a werewolf. ^^ Does lythari get a hybrid form as well? Or only normal wolf form?
