Make Sure I'm Not Messing Up :)
I would drop some of that health. 18,285 is really high for a S/D thief and you wont be really doing any damage. I don’t know what your traits are though. Get some more crit damage and crit chance. (ruby orbs 120 power, 4% crit chance give or take, 12 crit damage) or you can get 165 power and 100 precision from rune of the pack. Alot of people roll with scholar and they are the best damage you can get over 90% so thats up to you to decide if you stay that high often. I dont run them personally I was running pack runes now I run ruby orbs. For how you are set up if you really want that much health get runes of the pack for the extra 5% crit chance at least.
