Dexterity build. (chaos blade in replace of balder side sword will work also)
you will be using the shadows to your advantage in this pvp build. Apply buffs before every fight. Acid surge is used in order to drive enemies off, you usually won't hit them but they won't walk into it. Poison mist and toxic mist are used when you are backed into a corner or need to escape. If the enemy is in a corner then make sure you get them toxic or poisoned. The balder side sword is good for backstabs and getting in a quick and precise attack. Great combustion is used when in a tight spot or when enemy is running.
You don't have much defense so make sure you dodge most of their attacks.
(If needed you can switch out the black leather set for the dingy set instead)
