isn't so difficult
stats
str and dex: enough for your equip (maybe a bit more dex, cuz it makes your physical dmg higher)
vita - as much as possibel
ene you don't habe to place any points here, but up to 50 are ok
skills:
shadow:
venom 30
x-bow master 30
shadow-master 1-30
traps:
you don't have to skill traps, but i think they're good i you need another type of dmg
so skill the lighning trap Lighning senry+syns
Equip
you can use the assasin x-bow set (Black Death) or a Doubleshot Maschine+RW/Unique/Set combo if you wnat multiple shot
or
you use a X-bow with Faith/Broken Promise(i prefere BP) + RW/Unique/Set combo
and use Strafe
Here some RW/Unique/Sets i would use:
Boots : Imperial, they are really good for the posion dmg
Armor: Bramble, CoH,Fortitude or Humility in an Assasin Armor with +3shadow +3Venom or Shadowtrick
Helm and Belt: Blood
Gloves: the Gloves from Trang-Ouls set are really good with+ 50% Posion dmg
Amu+Ring: Ubers if you could get them, CC-Set for Poison dmg or Diva set (there're some other possible combinations of unique and sets)
Inventory: Shadow skillers if you find them, an +5 Anni, a Queens Call, Life and Death charm, etc.
Merc(use one A5 from lr/cgs)
Boots: Lysianns Eyecatcher
Belt: Blood
Helm: the one for barbarians with fana aura(if you don't use faith) don't know the name yet, look it up in itemlist or blood
Armor: ST, Humility, whatever you find
Amu+Rings: Diva
Weapon: Last Wish in a Thundermaul
Gloves: the gloves with 25% live should be good(don't know the name yet)
from your doll stash you should get Lower Resist, first cast it, then attack , everything what's still standing after this should be killed with traps
use Mindblast and/or Shadowmantle(i hope this is the right name, didn't play a assasine since i switched to english) in difficult situations
I hope i could help you, hf and gl
