Gandalf's 'Unlimited Powerrrrr' Empowered Smite Electro Scriers
 Psyker Build - Warhammer 40k: Darktide 

A build ported over from Victor after I edited his Electro Staff build to focus on the staff more instead, since he already had a Smite build with Shriek, that works to maximize it's damage potential, I figured I'd take it one step further and do the same on Gandalf now. His build was basically just an 'uber safe afk smite build' anyway, and that's no fun. What's more fun is trying to maximize damage by spamming crits, hitting things with your sword to stack Malefic, then unleashing the most powerful smite the world has ever seeeenn!

It's still smite though, so not exactly breaking records or anything, but at least with Scriers constantly funding peril Empyric Resolve doesn't feel nearly as bad when you're not smiting, and the Electro Staff does wonders for that as well. Funding toughness with crits thanks to mettle too is quite nice, while said crits also keep you form getting chipped as much thanks to Empathic Evasion. So overall I think this is the 'better' of the two smite variants, allowing you to make up for the deficits while also just maxing out it's damage. Though the lack of soulblaze is felt, but your team likely already steam rolled through all the enemies by the time you would have shrieked these days anyway, so nice to just stack up all your damage up front.

Point is to smite, Electro staff anything with armor your smite can't deal with. And stab things with your sword when all that's left are the stragglers/when you want to stack up Malefic for your next big smite. I take Charged Up to make sure one can 'spam smites' if they need to, primary so one can 'force push' the wave with it/drop it when things get close then immediately start it up again for no cost to you. And I take Seer's to help keep the time between your ability to smite and when Scriers is off cooldown to a minimum, and now thanks to Scriers quelling, you can usually finish a Warp Unbound smite, quell, start another one, and have Scriers ready to activate before that smite even ends, creating an infinite loop. 

For those that truly don't want to play the game, and want to live the Palpatine life, this is your build. (if you do want to play the game a bit though, light light light heavy is your sword combo, or Push Attack into a horizontal sweep light attack into a heavy to finish anything off. Heavy attack any large thing that moves, and you'll be golden with your Malefic stacks to nuke the wave, or go about smiting it). The build is actually rather 'freeing' in that due to how it works, you can basically pick any of the tools you have at your disposal and focus on it, and it will do well. So whether it's stunning the wave, staffing a big target, or swording everything in between, you'll be able to have a good time. One of the only builds that makes Empyric Resolve not feel terrible, so I keep it around for that reason too.
