I don't have much info myself as I haven't played a shifted since after the revamp of the class.

But I remember my friend got the Pachyderm and this one battle fellah got really upset trying to fight that one.

So get a pachyderm and try it out and let me know if I'm wrong =)

Edited to add:
And here is a log of it in action. It's not getting any attacks in during normal combat but still does well I would say. (as stated in my previous reply)
