Horde-bane: Righteous Flame Zealot H40
 Zealot Build - Warhammer 40k: Darktide 

This build has been tried and tested in Havoc 40.

Since Zealots have efficiency issues compared to other classes, this build focuses on a playstyle where the Zealot does useful work as often as possible. A Survivalist Veteran lets this playstyle really shine.

Artemia Mk III Purgation Flamer (Maniacs, Unarmored) 

The flamer’s primary attack is your bread and butter, u s e  y o u r  a m m o! 

Using the flamer smartly is how you make the biggest impact. Remember to a l w a y s reload when you have the spare time. 

Use it to:

• control hordes
• hold chokepoints 
• push
• keep pressure of the team 
• prevent ambushes

You need good positioning to get the most value out of the primary attack. You may be surprised by how long a full magazine can last when you use it conservatively.

__________________________________________________________

The flamer's secondary attack is for:

• heavy mixed hordes
• "Oh fuck" situations
• dying in glory

The strength boost from Blaze Away  and Overpressure  are incredibly helpful here. A half-mag dump, meaning 16 out of 32 ammo, can kill almost anything in seconds, except Crushers and monstrosities. The talent Thy Wrath be Swift  is necessary to make sure your mag dumps are not interrupted.

Chorus of Spiritual Fortitude 

Use it to create 

• favorable positions for your team
• as a setup for the flamer 

You can use primary attack → Chorus → reload, and then repeat. This gives you roughly one minute of effective battlefield control.

Atrox Mk VII Tactical Axe (Shred, Headtaker) 

This blessing pair is a no-brainer. It gives damage, crit chance, and maximum cooldown reduction.
By simply hitting enemies as much as possible, you can reduce the cooldown of Chorus to roughly 30 seconds, even without any other cooldown-reduction auras. Do not forget to throw in a couple of special attacks in between LMB-spamming for extra stagger.  

Weaknesses

The main weakness of this build is the Crusher . Do not use your flamer on these, instead use your main weapon
