Plasma Gun Veteran (Current)
 Veteran Build - Warhammer 40k: Darktide 

This is my current favorite version of the Plasma Gun Veteran and likely the best Veteran build to use in endgame content. Kudos to Tanner Lindberg for allowing me to turn his build into a short - the only reason this build page exists is to elaborate on weapon and talent selections.

Pros: Great special sniping, cleave, and single target damage. Highly mobile and tanky in the correct circumstances.

Cons: Not as good at boss killing as Lasgun builds and doesn't have the crazy uncapped AoE potential of grenade Veteran builds.

Weapons

I highly recommend using weapons that have the Uncanny Strike blessing such as the Duelling Sword, Knife, or Shovel. I like to run 5% crit and 25% Unyielding Damage on almost all of my weapons since the Veteran Talent Tree allows you to meet nearly every "breakpoint" extremely easily. 

For your Plasma Gun breakpoints are less important nowadays because of all of your damage increases. I like to run Flak and Unyielding just in case, but you can also easily run Crit and Unyielding. For blessing you still want to run Gets Hot and Rising Heat because they're the most efficient blessings to choose. Additionally this build can run the Zarona Mk II Revolver as well, if you do I recommend using Point Blank and Hand Cannon. 

Curios

For Curios I run a balanced setup with 2 toughness and 1 stamina. Grab Ability Cooldown, Stamina Regeneration, Gunner Damage Resistance, Sprint Efficiency, and Block Efficiency. You're going to be using your ability whenever it's up so you really want as much cooldown reduction as you can get and stacking stamina benefits makes surviving much easier. Stacking toughness curios allows you to mitigate more damage in the long run.

Talents

Starting off take Out For Blood, Confirmed Kill, One Motion, and Close Order Drill. We want to reach the bottom of the tree ASAP and this offers you enough toughness regeneration, weapon swap speed, and toughness damage reduction for this entire playstyle to play smoothly.

Next grab the Shredder Frag Grenade, which is great for crowd control and area of effect damage. Then we build into Superiority Complex, Iron Will, and Trench Fighter Drill for more damage, survivability, and attack speed. 

We have our first divergence in the tree where depending on your melee weapon you will either want to choose Field Improv or Serrated Blade. With the Combat Blade you don't need more bleed so go with Field Improv and with the Duelling Sword or the Shovel go with Serrated Blade for the bleed. The Shovel Serrated Blade combo is REALLY GOOD, try it out!

After Catch a Breath choose Survivalist as your aura for the ammo efficiency and Demolition Stockpile for unlimited grenades.

Voice of Command and Duty and Honor are still a must take for nearly every Veteran build because the crowd control and extra max toughness offered by this combo is too good to pass up. You can certainly take the other abilities but I don't recommend it.

On the bottom left side of the tree take Precision Strikes and Fully Loaded. This extra damage and ammo increase the efficiency of Survivalist.

In the middle of the tree take Demolition Team for more grenades and Tactical Awareness for more cooldown reduction.

Lastly take Reciprocity, Desperado, Agile Engagement, Skirmisher, Exploit Weakness, and the Weapons Specialist Keystone with Always Prepared and On Your Toes. This provides all of the backbone for the build as everything here increases damage, crit, mobility, and action economy efficiency. This last part is important because the time that you spend reloading or waiting for your toughness to come back is crucial in endgame content. If you can eliminate or mitigate those two things you can always focus on doing damage and not dying.
