I am Death (The allrounder Skitarius)
 Skitarii Build - Warhammer 40k: Darktide 

Electrocute fleshbags. :)

This build attempts to mix crit chance, electricity, frontline defense, and having the utility of Servo-Skulls. You can kill bosses pretty quickly but not as quickly as other builds. This build is more meant for dealing with hordes, armor, gunners and specialists. 

Hordes - Clear with melee

Armor/Shields - Use weapon special (great for mixed hordes)

Specialists - Gun

Boss - Gun kinda melts them and you rarely have to reload with Charmed Reload & Cavalcade , which is good cuz it's a long reload.

Talents:

Blitz:

Artificer Servo-Skull: I have another reliable shooter on my team. I rarely use the Purgator Servo-Skull and use Medicae Servo-Skull a lot more, I play with mostly randoms, so it's pretty helpful. Also, you can use it on someone who is captured while you fight for your life and if you go down, the Servo-Skull will still get the other player up. Now you are still getting beat up and they can get everyone else up. 

Ability:

Voltaic Emitter: I like shocking things, but also I can get +4% crit chance when I use all the charges (Last Stand Relay) and when I gain a charge, I gain 12.5% Strength (Sequenced Charge). I also have +20% damage to electrified units (Weakness Analysis Doctrine  & Retribution Conduit ). The damage on Retribution Conduit  for additional charges is good too, and will give me an additional 5% every time I gain a charge stacking with the 12.5% strength. 

Keystone:

Flensing Protocols: This is for defense and +1.5% crit and +1.5% attack speed stacks with Servo-Sinew Surge and every time I use my Ability, I ensure I have 8 stacks (Enhanced Capacitance Protocols & Honed Dissector )
