Kantrael Infantry lasgun sniper build
 Veteran Build - Warhammer 40k: Darktide 

a build for people with really good aim and good target priority

demo team and field improv are too valuable to give up for what they provide

good damage against bosses, but nothing magical (unless using bolter)

very ammo efficient

for crushers/maulers you can use either dueling sword of shovel (both really good), depends on which weakness you want to cover more.

Shovel for if you find yourself surrounded by a horde frequently (decent anti-crusher/mauler)

Dueling sword if you want to easily deal with crushers/maulers, especially for those rare games that spam them out constantly so you don't feel useless the entire time (decent horde clear)

crushers/maulers by themselves aren't scary, only if accompanied by a horde (grenade) or elites/specialists (gun)

often times you can just let teammates deal with them while you take out the actual threats (gunners, trappers, bombers, etc)

important to also keep an ear out for if you are about to get hit in the back while sniping and dodge in a timely manner while continuing to snipe because taking out ranged threats your team can't deal with easily are usually first priority

I use the mg1a lasgun because it can one shot the vast majority of important enemies and it's the only weapon variant with a proper sight attached

other one shot weapons are recommended such as the helbore and revolver

Bolter is also an amazing choice, but the talent tree will need some rearranging:

Exhilarating takedown -> volley adept

precision strikes&shock trooper -> bring it down!
