FAST WIZARD
 Psyker Build - Warhammer 40k: Darktide 

The ultimate in high mobility staff builds. You'll mostly want to keep spamming your staff's primary fire, while wielding your melee weapon while sprinting to benefit from its high mobility, but do make sure to fire a fully charged secondary attack every now and then to trigger the damage bonus from Channeled Force to your staff's primary fire. Between the movement speed bonuses from Mettle, Warp Speed and Disrupt Destiny you can expect to be much faster on your feet than almost any enemy in the game(I believe only mutants, pox hounds and monsters are faster) so long as you keep Scrier's Gaze active and you keep shooting marked enemies, which you should be doing anyway.

This build has sky-high ranged critical chance

•7.5% (Psyker's base critical chance)

•21% (Electro staff's crit bonus at 80%)

•5% (weapon perk on staff)

•5% (passive node)

•5% (aura)

•up to 20% (Warp Nexus weapon blessing)

•20% (while Scrier's Gaze is active)

Which adds up to a whopping theoretical maximum of 83.5%. Needless to say, this makes the Surge weapon blessing work very well, and you will trigger Empathic Evasion consistently enough to keep you safe from ranged enemies as long as you keep shooting back.

As far as melee goes, you don't just have extremely high movement speed, you also have Kinetic Deflection allowing you to block using peril, as well as +6 stamina on your build(+3 from curio, +3 from talents), Anticipation for better dodges, and your melee weapon has a parry as its weapon special. Between that, and the critical&weakspot damage bonuses in the talent tree, this build is also quite robust in close combat in terms of both offense and defense.
