Shockless Skit
 Skitarii Build - Warhammer 40k: Darktide 

Alternatively titled: Who Needs System Shock ?

This build tries to hit as many flat damage increases as possible, minus any linked to electrocution.

Take advantage of delicious status effects from the phosphor pistol and you'll have 80%+ uptime on Weakness Analysis Doctrine . Phosphor's innate 15% effective brittleness mod and Supercharge on the Branx Mk VI Mechanicus Power Sword  (MPS) supply plenty of armor negation for killing hardened targets that you can't immediately chordclaw to death. (Note that you do not need Infernus to proc Weakness Analysis Doctrine on targets you've shot - hitting an enemy with the innate phosphor debuff is enough. I like the DoT synergy, but it's optional).

Chained Deathblow and Surgical will have you activating Flux Conduit Build-Up and Power Redistribution Uplink very frequently, without needing to spec into Flensing Protocols . Both crit proc talents grant their bonuses over time, so you only need to crit once every 3-4 seconds to maximize their uptime, and you should be able to hit that comfortably. You'll be poking a lot of heads with the MPS, so in practice you'll often have a ~33% crit rate rate in hordes (+7.5% class innate, +6% from Last Stand Relay , +20% from Chained Deathblow). After the tweaks to Decapitator in 1.12.4, it seems like a great companion blessing on the MPS if you want to lean further into crit effects - more finesse means more headshot and crit damage, which means you're more likely to keep procing it. Charged H3s can conditionally oneshot maulers :P Devastating Strike is less spciy but it's fine too, especially if you prefer not to expend any charges while hordeclearing.

Toss in a horizontal chordclaw with Axial Slash during hordeclearing to keep  Moebian Conductor activated and allow Sequenced Charge to activate, and you'll usually end up making back a bunch of capacitance and toughness from weakspots. If you want to maximize DoTs or provide some entertaining scab captain damage, you can take Probing Strikes  instead, but you'll need to be much more intentional with your activation and aim to be as effective otherwise.

Variations

• Absent the crit/attack speed bonuses from Flensing Protocols and Servo-Sinew Surge, I prefer the MPS over paired transonics. Both weapons are excellent, though, take what you like.
• If you want to absolutely maximize your own damage output: swap Assassination Protocols for Hydraulic Impact , then swap keystone to  Flensing Protocols with Servo-Sinew Surge and Honed Dissector . I prefer the potential for stacked damage bonuses and AoE de/buffs, but up to personal preference.
• I run Assassination Protocols because I hate reapers, plus the node boosts phosphor's innate DoT and Infernus damage against them and other big targets. You can probably swap it out, though.
• Hydraulic Impact is probably the most salient node missing from the build as is. For MPS, it can help skipping captain phases (chordclaw hits twice and will trigger shield, MPS H3 is the single highest damage hit available to the class with H1 close behind) and for transonics it provides a welcome damage bonus that helps mitigate issues with armor. If want to lean into single-hit damage on the MPS, take Sunder instead of Supercharge .
• If you feel like you're lacking in TDR, you can swap a node for Threat Detection Imperative. Progressive Plating Matrix can also be taken in exchange for Adaptive Combat Calibration .
• I don't find Electro-Strike Conduit particularly useful, but if you value the safety the stun provides you can get it in exchange for Binary Ballistics Protocol or Auto-Repair Doctrines . May synergize better with transonics due to their higher hit and crit rates.
• Despite the guide name, swapping Chordclaw for Voltaic Burst is potentially an option if your team is sorely lacking in shooter suppression or AoE CC. That said, you're sacrificing a) synergy with crit and weakspot nodes b) burst hordeclear c) a fun theme :'(
