Empress set Preparation.

Personally I have a 34 dex top+bottom, 15 dex earrings & shield that I can temporarily equip, and that pretty much covers it. Although that's with 35 base...

My nemesis is the Taru Spirit Cape (req. 85) since my attack gear doesn't add much dex. Classes with +dex skills are fine, but eg. my Aran? Nope, not going on unless I make about 25 dex worth of dex gear appear in place of str/atk.

arans have it harder indeed, they don't get a +30 skill on union do they? and the amount of good endgame tradeables is little (untradeable shoulder, helms for the most part, pendant...)
