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

This build has been tried and tested in Havoc 40.

Since Zealots have some 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 you be less conservative with flamer ammo and a Nuncio Aquila Arbi allows for very aggresive melee gameplay. 

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 while LMB-controlling.

__________________________________________________________

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 absolutely necessary for this build. The talent Annoint in Blood  give up to +25% reduced the further away you are from the target and is optional though.  A half-mag dump, meaning 16 out of 32 ammo, can kill almost anything in seconds, except Crushers and monstrosities.

Fury of the Faithful + Until Death + Zealous Pilgrim

When you hit 1hp, you need to manage your cooldowns for Fury of the faithful and Until Death

• Go in and out in cycles. 
• Don't hesitate to use your Until death timer for a Flamer mag-dump. Until death lasts for 8 seconds now which gives ample time to clear a horde with holy fire.

Munitorum Mk II Relic Blade (Unyielding, Carapace) 

You can go after any target and to serious melee damage with this build. 

• Both Captains and Twins can be killed in 1 shield break if you time Holy Tools correctly with Fury of the Faithful, provided you are at low hp.
• You have a  l o t of cleave with the sword when it's charged up so use heavy attack chains on heavy armor hordes.
