Meta Chainsword Blender
 Zealot Build - Warhammer 40k: Darktide 

Build Notes:

• Thy Wrath Be Swift can be taken if you use Piety -> Stalwart and drop the four nodes under Sustained Assault. This will make you more tanky, but you will lose significant damage and dodge distance. (the IJ keystone gives you stats that the tooltips don't tell you about. Thanks FatShark!). However, this does mean you can drop shred for Rampage. However, I have more success personally with IJ.
• Boltgun can be taken with different damage oriented blessings, but puncture and shatter synergize very well together as the armor reduction affects bleeds damage. It is mainly used to snipe specialists or kill packs of Crushers or Maulers.

Playstyle Notes:

• The Mk13 Chainsword is one of zealots strongest weapons. Just swing light attacks at everything and it will die, it has ridiculous damage.
• 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 Boltgun is almost exclusively for ogryns. Packs of crushers, bulwarks, and reapers that are too big for your melee to handle quickly are rendered a non-issue. Since you take throwing knives, you shouldn't have many ammo issues.
• 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:

• Don't use the Special Attack unless there's no chaff around, it sticks you in place and puts you in danger.
• Light Attack for hordes, Heavy Attack for single target damage.
• Wrath is taken so each light attack cleaves the entire horde, and Shred is used for critical hits bonus damage to armored enemies (ADM)'s.
