H40 Standard Charge Zealot | Mk II Relic Blade + Shredder Autopistol
 Zealot Build - Warhammer 40k: Darktide 

Shredder autopistol isn't a troll pick having a high mobility secondary can boost your survivability when you have a low dodge melee. Extremely so in comps where you want to be relying on your movement to live through gunner fire. Its also great boss damage + special sniping.

Obviously if you want to win take like boltgun or flamer because zealot ranged weapons are very balanced into H40s (:. Other options include Recon Lasgun, Vraks IAG, Heavy Laspistol, Bolt Pistol, Revolver, and Agripinaa Combat shotgun. Mobility picks are good for survival and game feel as they say.

Other than that if you know how to micro relic blade it will do fine, qq to turn off sword when not actively swinging and try to always be in melee combat with the sword on. Don't forget Cranial Grounding procs even when sword is overheated so swinging it into grunts can cool it off quite a bit faster. Conserve dodges and don't dodgeslide unless you need to etc. etc.

Use charge lock-on to peel from team and kill some stuff that's out of the way. And knife can kill specials further away if needed, relic blade charge is probably among the best frontlining zealot has as long as the sword is on.
