This build will allow you to easily manage in PvP battles with either daggers or swords. Granted, in most cases, you will want to use swords as you will more than likely not be using Backstab or Ambush, opting instead for Cheap Shot. Its benefits are mainly the use of Cold Blood on stun combos and the ability to recycle your abilities with Preparation.

You’re looking at some interesting combo options here. The standard stun-lock combo looks like this (see Section 2.4 for what the abbreviations mean).

CS, SS, Gouge, CB, Evis, Blind, Vanish, CS, SS, Gouge, CB, Evis, Blind, Vanish, CS, SS, Gouge, Evis.

That’s 2 critical strikes guaranteed from the Eviscerates, more than likely, both will be 5pts each, giving you a possible 4500 dmg from both. It will be less on high armor opponents and you might run into energy issues. Thistle Tea can help with that. You will also require a good amount of Fadeleaf for the Blind Poisons. This combo takes a lot of practice to master as the timing of the stuns is important but if you’re able to pull it off, odds are, your target is dead before you’re done. The single point in Improved Instant Poison is there simply for the need to get Cold Blood.

Alternatively you can chose to move a few points from Elusiveness to Rapid Concealment. Why?

In a PvP situation "blind" is a powerful tool. It gives you 10 seconds of time to bandage, get out of combat, restealth and land another cheapshot. Especially with laggy connections or when your opponent is on guard it can happen that you are unable to stealth and move away in time. Rapid Concealment gives you those two more seconds that make it a safe bet to use blind, bandage, restealth and count on another cheap shot.
