If enemy doesn't die, disengage and wait for an easier target. If the enemy is caught up in a fight already you can also use Toxic Barrage ultimate to apply more pressure.
Sets Explanation
Swamp Raider Great set to boost our Poison and Disease damage by 600 Weapon Damage.
Plaguebreak Applies a strong damage over time effect on the enemy, applies huge pressure on the enemy in combination with [Posion Injection]. Also if other enemies are around they get infected too.
Oakensoul Ring Applies a multitude of powerful Major and Minor buffs. Basically the strongest set in the game at the moment.
Kjalnar's Nightmare we only use one piece to give us extra Weapon Damage. You can also slot another Monster Set here if you don't have access to Kjalnar: Balorgh, Molag Kena or Kra'gh preferably.
Why Vampire?
Stage 2 Vampire is needed because we can use stealth without movement penalty due to Dark Stalker passive. Also Strike from the Shadows gives us extra Weapon Damage].
