Meta Dueling Sword Build
 Zealot Build - Warhammer 40k: Darktide 

Build Notes:

• Thy Wrath Be Swift and Faithful Frenzy can be taken if you use Piety -> Stalwart and drop the four nodes under Sustained Assault and Purge the Unclean. This will make you more tanky, but you will lose damage and dodge distance. (the IJ keystone gives you stats that the tooltips don't tell you about. Thanks FatShark!)
• Boltgun is also a decent ranged options if you aren't having horde clear issues or you have Assail / Purgation Staff Soykers who are going to evaporate all the chaff in the room.
• Boltgun can be taken with different damage oriented blessings, but puncture and shatter synergize very well together as the armor reduction affects bleeds damage.
• Dueling Sword also works with Precognition and Riposte.

Playstyle Notes:

• Abuse the Dueling Swords deadly headshot/crit multipliers using Uncanny Strikes and Thrust or Riposte and Precog to 1-2 shot dangerous enemies with heavy attacks while still having reliable horde clear with light attacks or light/special spam.
• Dueling Sword has ABSOLUTELY BROKEN dodge counts and distances. You can't die if you space correctly. Learn to kite backwards without cornering yourself.
• Your special attack staggers every non-boss enemy in the game.
• If you're out of stamina, use light attacks for horde clear and heavy attacks for single target.
• Gunner resistance curio are good, you are not Neo, you are not going to dodge hitscan bullets all of the time. All the other damage resistances can be dodged or outplayed much more easily.
• Stamina regeneration is better than sprint efficiency. You will get more 'actual' value out of it. You are not sprinting everywhere in a fight, and when you are, you usually aren't in a ton of danger.
• The flamer can melt even the largest horde in seconds. Annoint in Blood applies to your flame DoT, which is why you dump damage. It's useless.
• The throwing knives replace any need for a revolver or similar ranged weapon. They one-shot all specialists and ranged elites like shotgunners and gunners.

Weapon Notes:

• Light Attack or Combo: (Light Attack -> Special) for hordes.
• Heavy Attack for anything other than hordes.
• Move Tech: Sprint slide and use the momentum from your heavy attacks to sprint slide over and over without losing speed.
