Void Rend
 Psyker Build - Warhammer 40k: Darktide 

This build is stupid.. and by stupid I mean too fucking good for it's own good. IT IS VERY STRONG. IT IS VERY EASY to play.. and what's funny about it is.. no one knows to build it this way.. for one.. no one uses combat blades with void staffs. which is hilarious as it makes you able to get out of anything.. and I mean.. weave casting if you're not lagging is borderline OP.. but anyways.. for two.. it has so much armour penetration and debuffing for not only the team but for yourself.. your dagger.. can now just 1-2 shot crushers in a group once it's all combo cast debuffed down.. you queue it up right and they not only bleed/electrocute to death really fast but they also die fast on double drop down(push>>heavy.. it's fast.. also mix in the combos.. push>>to the poke regular..very fast.. applies lots and yeah I use the mark 3 combat blade here.. YOU DO NOT NEED mark 6.. in fact it's better for faster armour kill with max movement if you run the 3.. trust me) lol. and it's very useful for the team.. you have fast regen bubble and smite for flash smiting and dropping a bubble on downed teammates.. it lacks surge blessing and crit setup.. BUT.. it doesn't need it.. because you can ranged debuff so much with it that double shotting for damage is uneccessary. you can literally bolt down crushers with the right combo casting. it's fucking hilarious and probable one of the easiest builds to play next to the havoc purgatus build(also a very good build in havoc too).

IMPORTANT NOTE: In this build only and specifically you need to spam push attack your combat blade a lot(daggers have high innate crit). so not only do you keep perfect timing rolling this way for more warp damage but you also keep uncanny stacks rolling in which will up your armour pen and damage.. What I do is weave cast into enemies blasting there feet and push poking to keep everything rolling.
