Gandalf's 'Braced Shield' Empowered Rupture
 Psyker Build - Warhammer 40k: Darktide 

A build crafted from the 'synergy' that is having the ability to 'hold a wall in reserve' for whenever one needs it for Kinetic Resonance, this build is a build that primarily tries to make BB as effective as possible. A wall to slow down or even stop enemies so you can line up your targets, an extra charge for longer faster cast time, and fully speced empowerment so it will give toughness on cast, go even faster, and kill Ogies in 2 hits.

It's...fine, it's main issue is the fact that it can't generate peril what so ever. You can't even 'just idle with BB' since EP makes it cost nothing to cast, thusly making it never generate peril more often than not. This leaves you primarily spamming BB to get toughness or to get peril when it runs out for less effect, or just dumping your Braced Autogun for Toughness regen as well.

It works well enough though, and I like the theory of the synergies so I keep it around. Being able to use a Deimos with Executor and Uncanny Strikes is a great reason to use it too, since you can block bullets with the walls. Stacks with the warp attack on headshot, then just L1 H2 every armored thing to death you couldn't BB before it gets to you. 

The main point is to keep things away though, so try and keep things away! Or hide behind your walls and your team mates.
