What is the best dpm for Shadowers?

Thanks for the answers guys, yea i had a feeling full charged assasinate would deal some heavy dmg. However this wouldn't help too much with monsters who do super weapon defence (1 dmg) such as Zak or monsters who dispell. What would you suggest for stronger bosses such as Bodyguards, Zak, HT, Czak?

Just use Bstep+BoT or Bstep+Steal, these are your ranged multi-hit combo's.
