Gandalf's 'Blazing Voidblast' DD Shriek
 Psyker Build - Warhammer 40k: Darktide 

An intriguing build I thought I'd throw together, with the idea of using 'Blazing Spirit' on on the Voidblast staff. One could make an argument for Voidstrike too, but I feel that one's just strictly better with Surge, and I feel using both on such a long charging staff isn't the greatest idea.

But since surge doesn't work on Voidblast, it slots in pretty well! You have to keep track of your headshots a bit more and make sure to get your true aim's off with a big radius explosion, but otherwise? Just free fire all over the place! You can even go about spamming it and simply rely on the 12.5% chance to crit to keep the fire going to. 

It's not to greatest of builds, but it's fun spreading fire around without needing to use the Inferno staff. The DD proc's help the Deimos to absolutely DEMolish anything armor or larger as well. Warp attack to stack up uncanny strike and get a good few headshots in, L1 H2 to knock anything over and kill it in one to two hits. It's pretty good stuff, and a nice bit of novelty.
