Kasrkin Elite
 Veteran Build - Warhammer 40k: Darktide 

This is a high-skill Veteran build focused on weakspot damage and crits using the Infantry Lasgun. It rewards consistent headshots with strong elite and specialist removal, excellent ammo efficiency, and overall ranged effectiveness.

This build is designed around the Kantrael MG VII and MG IX, as both thrive with precision shots. The MG IX hits harder but fires slower, while the MG VII offers the best overall balance of damage, stability, and fire rate for sustained pressure. The MG IIb is not considered due to lower damage output, the flash from the lasers being a detriment to accuracy, and excessive input strain for minimal payoff. However on PC, if you use the automatic shooting mod, it could be viable. Take +25% Damage to Flak and +5% Increase Ranged Critical Strike Chance, for the perks, and Headhunter + Deadly Accurate for blessings to build reliable crits and double critical headshot damage.

Melee is handled by the Achlys Mk VI Power Sword, chosen for its strong damage profile, its fit as the sort of field-issued blade a Kasrkin Elite would carry. Take +10-25% Damage to Carapace Armoured Enemies and +10-25% Damage to Unyielding Enemies as the perks, and Power Cycler with Brutal Momentum for the blessings, so the extra chained energised hits and weak-spot kills that ignore hit mass can open armored threats and still carve through a poxwalker horde.

Use the Survivalist Aura (replenish 0.5% ammo for you and allies in coherency whenever any of you kill an Elite or Specialist, and only once every 5 seconds) for steady team ammo support. It is the augmented form of Scavenger, and with the large ammo pool on the Infantry Lasguns you will rarely need to stop and stock up on ammo tins or stashes.

Finally, take the Keystone: Marksman’s Focus, along with the modifiers Chink in Their Armour and Long Range Assassin. Marksman’s Focus grants 3 stacks of Focus on ranged weakspot kills (up to 10 max stacks, lasting 5 seconds, refreshed on weakspot hits and decaying one at a time). Each stack provides +7.5% Ranged Finesse Strength and +1% Reload Speed. Chink in Their Armour adds +15% Rending when at or over 10 Focus stacks, while Long Range Assassin increases maximum Focus stacks from 10 to 15.
