"Righteous Warrior" Zealot Havoc 40
 Zealot Build - Warhammer 40k: Darktide 

Role

This build is Havoc 40 viable, designed for frontline support, with strong team stabilization and mixed-horde control. Main tradeoff is lower personal damage and attack speed than a Relic Blade build centered on Fury of the Faithful or Inexorable Judgement.

Situational Equipment Adjustments

Use the Flamer by default because it provides mixed-horde control and Brittleness support.

Switch to a Bolt Pistol, revolver or another precise ranged weapon only when the team lacks reliable answers to distant gunners, snipers and bombers. That swap should depend on team composition rather than being a permanent change.

Why Purge rather than Abolish Blasphemers?

• Purge the Unclean: +20% damage against Infested and Unyielding enemies. 
• Abolish Blasphemers: +15% damage against all Elites, making it more broadly applicable during Havoc’s dense elite waves. 
• Punish Impiety: push-follow-up attacks grant +10% melee attack speed for five seconds, directly addressing the Mk X Relic Blade’s slow attack cadence. 

Purge remains valuable for monstrosity damage, but main function is controlling mixed elite packs and supporting the team, not maximizing personal boss DPS. The persistent attack-speed benefit is generally worth more than Purge’s narrower damage bonus.

Infectious Zeal may be controversial, but now that it can be selected alongside Righteous Warrior, giving three other rejects +10% crit chance nearly all the time is a very powerful buff for just one talent point.

Tips

Cut priority: Thy Wrath Be Swift first, Purge the Unclean second, Abolish Blasphemers third. 

Example:

• Thy Wrath Be Swift → Enemies Within, Enemies Without
• Purge the Unclean → Punish Impiety
