question regarding backstab/sneak attack

[l0rdza0n]

question: does backstab/sneak attack get better the more a TH levels up?

or is it the same..

i know, stupid question.. but FF is different from normal rpg's.. so i don't know if the same multiplier system works

so any high level thief out there know for sure?

mainly i plan to make my main a TH which is why i need to know now..

I got my level up to 46 yesterday. my numbers might give you some picture....

I hold 2 bone knives. A HQ one in my right hand and a normal one in my left hand.
my average damage from a single hit is 16-20.
my damage when successful sneak+decieve = 250.
in a renkei, seank+decieve+ViperBite WS = always 360+. Average 420. Highest I have done was 570. and adds 150-300 from renkei effect.

I do less damage in a single hit. but when it comes to renkei, I am the number 1 damage dealing right now.
