Am i to assume this is a typo on the card, or is the Werewolf form permanent duration?

Since there is no erratum about it in the official FAQ, we play it as is, i.e. its effect is permanent, where the caster can choose to discard it during his turn.

We did the same. Just wondered if there was any official answer ;-)

I do this way too. And like Angus says there isn´t any clarification in the FAQs. Think that this spell is worse than carrying a speedstone plus an Mightstone (and both are permanent too), you punch for 1 physical damage less and you can´t cast anything but counterspells. It isn´t too powerful in my opinion.
