scriers bfgs melee psyker
 Psyker Build - Warhammer 40k: Darktide 

pretty standard melee psyker build. I think the only potiental changes is either true aim, warp speed, and quietude could be dropped for focused warp, you can choose which one. quietude is nice on scriers builds, and gives you a nice amount of toughness. the interaction between just a dream and quietude is really nice, essentially refunds toughness for losing toughness. true aim i like because it gives guaranteed crit for mettle and empathic evasion when pull out laspistol to shoot something. crits also 1 hit to head some specials and shooters. warp speed isnt necessary but the movement speed is so nice for slide tech with blaze force greatsword. other talents I think could taken instead of any of these would be warp splitting or battle mediation. battle mediation is will boost scriers length if you want more of that but i find by crack of bone to be much better and do enough for me. if you want a super boost to scriers, empyric resolve will greatly extend scriers but the toughness gain loss kinda sucks to deal with so i dont take it. 

I use laspitol bc i dont want to have to worry about peril when i decide a special needs to die right now and my peril is already critical. also it has better movement than the electrokenetic staff and you can actually outrun hordes with laspistol. plus i find that staff to be soooo boring to play. i dont like m1 spamming balls at everything, just dont think its satisfying.

theres an arguement for using shred instead of unstable power on blaze force greatsword scriers builds but i found that my uptime on unstable power stacks is pretty good and will do more for me then the increased crit. i also whif a lot and it makes me manage my shred stacks in a way that i dont enjoy. so unstable power it is for me.
