I agree Rango should be difficult to kill being a tough dessert lizard with a huge ammount of luck, but this is way too much.
And what's his weak spot? Ophelia has low willpower, Somer has lousy melee and low survability, Zoraida doesn't have a decent damage dealing spell or weapon, your Rango doesn't have any weakness that I can see...
