here's bes build:
aimed:5/5
nox: 5/5
veil: 4/5, no explosion
traps: 4/5, no explosion
dex, damage 5/5
str int 4/5

it surprises me that so many rogues favor sp over nox. Nox is essential in elites. It lasts for 8 seconds, does 75-100 damage a second and attacks up to 6 mobs. That's a ton of damage. Charge a veil as ur running into a group, tap traps, tap aimed, charge nox, tap aimed, charge nox, etc. By doing this u don't miss out on an aimed shot and ur dealing the most damage possible. Imo, razor sucks. traps does more damage than razor does.
