With similar stats and gear ('cept I used BGS), I killed him with tort + titan (though I think Kyatt is better?) I used piety, and I hear leeching is better than piety. Since you have SS you should be able to beat him. If anything, at least give it a proper go and see how close you get. You can then decide if it's worth trying a time more or two, or just put it off until you get the turm. SW cape is great, you'll love it when you get it.
