triumph emblems or frost? I'm assuming you're talking the former.
it really depends on your style, but if I were you I'd try and get the T9 helm. It has expertise and you currently have no extra expertise; it would help some with your damage. Other than that you've mostly bought what you can. The offset helm (hood of lethal intent) is another good choice, as is the offtier shoulders, but neither are super required right now.
