'bout my build...gnerally it is based about creative use of cloaking, hide, grimtooth, stone throw, meteor assault, venom dust and throw knife..oh and SB too, as finishing move. It's much better "duel" build since you have possibilities how to kill anyone without need of link or EDP. Takes some experience with RO, you gotta know your enemy's weakness. But then, pretty much anyone can be dealt with. At WoE, it is also about your ability to evaluate the battle and pick your target.
Stats (without any outside buffs): 120 str, 75-90 agi, 60 dex, what's left goes to vit. About 12k-13k hitpoints with right equip, enough to survive if you aren't stupid.
Equip: Little more than SB build, forget defensive equip except thara for switching sometimes. You need from two to four weapons, minimum is +4 boned infiltrator and jur or slotted ele katar with various status cards (metaling is one of my favs, thana maero is top if you get it, sleep and curse are next two most interesting). Bloody Roar, and empbreaking katar are also good to have.
Time is pressing me, I can elaborate more later if you want.
