Gandalf's 'Empowered Rupturing Force Sword' Shriek
 Psyker Build - Warhammer 40k: Darktide 

A build that was the culmination of like 14 different ideas before I finally centered on one just now to post it. The initial inception was the thought to make a build that let you 'sit behind your shield', and just sit behind a Force Shield forever, occasionally Shrieking to burn everything down.

This was...a build, it worked, but it's both boring, and everyone kills everything so the only time it ever mattered was when an overhead was coming my way in which case it broke my block and ended me anyway. So then I thought to pivot it to more of a melee build, but I really wanted to keep using the Force Sword V since I didn't have a melee build for it exclusively.  But thennn I wanted to keep the Bolt pistol on it for the same reason, but had issue dealing with armored targets, but then remembered empowered BB is a thing and I didn't have one that used Shriek with it. But THEN because of all the fire talents I didn't have enough points to take it, get all the Empowerment I wanted, AND still get all the toughness nodes so that the curios above let me get to 202 toughness.

And then I finally said 'f it, it's a raw damage build' and everything finally worked. Max cooldown so one can shriek often, in between shrieks one constantly warp slices with the Force Sword V to get back peril. One Empowered BB's any armored target, or swaps to the Bolt pistol in a pinch, with it also being used for move speed and as a spacing tool with lethal proximity.

That's mainly it, it's a simple build. It functions well enough, Warp Rupture isn't the greatest but it's 'on brand' and works well enough, and that point doesn't exactly fit anywhere else that would do better. You can hide behind your Deflector whenever you need to, crit isn't the point, and one point doesn't get you to attack speed, so it all works fine enough. And is the only Empowered BB Shriek build I got...so yey!
