Some Idiots Demonhost Obliterator
 Zealot Build - Warhammer 40k: Darktide 

Welcome to Some Idiots guide to making bosses go pop. This build is mostly a meme, but can be used up until hi-havoc provided you're decent at the game. This isn't even a guide unlike my other builds, I just felt like putting up a properly usable version of the usual DH 1-shot builds you see around, cause tbh some of the other ones on here made me scratch my head.

The choices are mostly self explanatory, I've just dumped as much as I can into backstabs and weak spot hits. while still grabbing enough general utility talents to make the build feel somewhat pleasant to play. Against the Odds is the main talent here making the hammer viable in higher difficulties, Cleave from any source is amazing and allows the hammer to hope to deal with hordes rather than bouncing off them like a squeaky toy. You still have a Flamer here in case, the Thunder Hammer is still the Thunder Hammer, but I've swapped off the usual +carapace and Penetrating flames for more raw damage against other targets since your Thunder Hammer should be your main source of anti-carapace in this build. 

As for why we've dumped Restoring Faith and Bleed for the Emperor they're mostly just unneeded nodes that hurt our gameplan more than it helps us. You're playing Martyrdom builds on 25% or less HP anyway so Bleed for the Emperor will maybe take effect for 1 hit and Restoring Faith just makes sitting at the proper HP amount more difficult due to the slight regen. You don't want to be sitting in barrel flames trying to take damage, only to step off and accidentally regen back above the next wound because you didn't time it right. 

Because we didn't take the prior mentioned talents we're forced to go with Martyr's Purpose but as long as you're making use of Perfectionist then this shouldn't be an issue.

Unseen Blade is a talent we've also skipped because it doesn't work like how it says it does. You need to realize that by "Enemies not targeting You" it actually means "Enemies targeting another Player". This talent won't work if an enemy isn't aggro'd on anyone like a sleeping Demonhost or an enemy you've snuck up on with Shroudfield, you have to wait for it to target a teammate before it can be used. It's still usable but it's also skippable.

Sadly this build isn't quite as consistent as it was before the zealot update. They took away the ability to double-hit with Shroudfield so there's no more 2-bonking a boss to get the kill guaranteed or killing 2 Crushers in 1 cast.
