As Enarn I think it was #3 by virue of duo. My barrier was a matter of walking to it. Shields a grab and flee. Aura... think my source on that one was a two spell fight. This was one of the very few mages I have ever played where I pretty much always had wands, even though I've known dozens of spots with other characters too. One good thing about wand knowledge, doesn't die with your character.
