Crit Rushdown Las
 Veteran Build - Warhammer 40k: Darktide 

Heavy Laspistol/Catachan Sword Critical Dodge Spam Build

PRE WARNING:

"This Veteran build cannot regenerate grenades passively at all, unfortunately you're gonna need to be picking up the nades yourself if you want or need them*

This Laspistol is going to be taking down most Elites/Specialists in 1-3 shots max, including crits/burn damage on top. the Deadshot Talent is going to help get those critical hits you'll very much want and a bit of bonus accuracy on top, you'll want to be dodging and sliding around a lot and be very mobile to bolster that critical chance even further with the Reciprocity Talent which stacks up a ton, the Desperado Blessing on the Pistol itself helps us out a lot here too.

Some tips for the Deadshot Talent we're using and the build in general:

-The Laspistol doesn't particulary need to even ADS since it's a laser weapon with no recoil and it's crosshair is already so tight as is, so don't always feel the need to waste your stamina aiming down the sights for Kills/Crits on mobs because you really won't need to at all

-The Duck and Dive Talent we're running is really going to help the Stamina management with Deadshot's ADS Stamina drain, remember to always be mobile and dodging around somewhat frequently just incase by chance literally any gunner is shooting at you to replenish 30% of your maximum Stamina if you're needing extra

-The Catachan Sword is somewhat underrated here since it can deal with almost any threats coming directly from your FoV with it's powerful Parry special action attack (Alt Fire button w/ Sword) which deflects all enemies attacks and deals a decent chunk of damage back to them to them in return, esecially with the critical hit chance we're running

-If you so happen to be out of grenades for Crushers/Bulwarks, I'd highly recommend parrying them (you can parry every attack EXCEPT the Bulwark shield bash I believe, Crusher's overhead is inconsistent) with your Sword so you can create some space then swap to our Laspistol (the One Motion Talent thankfully also helps us with this) and try to shoot and maybe kill another low tier mob nearby you happen to spot, if you managed that switch back to your Sword to finish them off if there's only one on you, even if that fails you, you can always fall back on your Infiltrate Ability with a surprisingly short cooldown to either get you out of there completely or likely just give you the damage buff you needed to survive

Some additional tips for the Laspistol: 

-Ammunition shouldn't be any issue here at all as long as you're hitting those headshots/critical hits as much as you possibly can, you'll pretty much never run out of ammunition for it thanks to the Shock Trooper Talent which allows us to not waste ammo with the Laspistol as long as we're getting critical hits, then the added bonus of the Fully Loaded Talent on top of that, realistically you'll only be needing maybe a couple of ammo boxes max throughout and entire mission (if it's a longer one) for when you happen to be missing some shots here and there, I'd also personally recommend Ammo as your dump stat here on the pistol because of this, mobility is very useful in this game
