Redline Chordclaw
 Skitarii Build - Warhammer 40k: Darktide 

Use any weapon and Curio you like, and swap skills around to fit your needs.

(This is my first build and my first post. I don’t have deep insight into which skills might not be working properly or what is currently meta. I simply went with what sounds good and is fun to play.)

Playstyle

This build revolves around using Chordclaw Strike in combination with Redline Capacitors — tap the ability button for a sweep Attack, or hold it for massive single‑target damage.

You are a tanky support. Use your Medicae Servo-Skull to revive teammates and for data interrogation, and provide your team with extra Toughness and Stamina through Power Overflow and Data Sensor Protocol. 

You can also assist your teammates while incapacitated and grant them additional damage resistanceand stun immunity. Use Chordclaw Strike for crowd control, and rely on your heavy Chudclaw melee attack for tanky targets such as Mutants, Crushers, and Bosses.

Keystone + Ability Modifier

Resource Optimisation Canticles +1 Max Ability charges and +1 Redline Capacitors Max Stacks

Surge-Extension On gaining a Redline Charge, you replenish 25% Toughness over 5 seconds.

Redline Capacitors up to 2 charges with Resource Optimisation Canticles, gaining 5% damage reduction and 5% capacitance generation this Stacks up to 4. With the ability modifier Satiated Steel and the ability keystones Flux Conduit Build-Up + Augmented Power-Cycle, killing an enemy can generate 47% - 62% capacitance over 12 seconds.

Electro Chordclaw Strike 

Electro-Strike Conduit gives Chordclaw Strike the ability to electrocute enemies. System Shock applies 4 stacks of 2.5 Brittleness. Spamming heavy melee attacks against bosses is a legitimate strategy. When fighting shielded bosses, wait before using Chordclaw Strike — deplete their shield first.

Sequence Charge

Sequenced Charge You are going to use and restore a lot of Charges during a run, giving you high uptime. Having an ability that grants 12.5% Strength for 10 seconds is a no‑brainer compared to Target Prioritization Psalms.

Moebian Conductor 

Moebian Conductor grants +15% damage on ability use. Since you can trigger Chordclaw Strike very consistently, these +15% apply to all damage you deal, giving you a high uptime on this buff.

Hydraulic Impact

Hydraulic Impact provides +15% heavy melee damage and makes you uninterruptible — very strong against hard‑to‑kill enemies.

Uncapped Arrestor and Sustained Assault 

Uncapped Arrestor Successful Melee Attacks  2,5% Melee Attack speed for 3 sec 5x

Sustained Assault  Successful Melee Attacks  3% Melee Damage for 8 sec 5x

You gain these stacks very quickly, and both effects apply to your melee weapon and your Chordclaw.

Aura 

Chordclaw Strike  provides 50% Rending, and Adaptive Combat Calibration grants 30% Cleave while above 50% Toughness (which is easy to maintain). If you add the aura Foe-Render Creed, you reach 57.5% Rending and 30% melee Cleave, plus an additional 15% Cleave for both ranged and melee attacks.

If you want even more Rending, swap skill points into Capacitory Limit Override for an additional 15% Rending while above 3 Charges.

Defence

These are some defensive notes that work well with the melee playstyle of this build. Focus down priority targets, clear hordes, and sustain both yourself and your teammates.

Chordclaw Strike is perfect for Power Redistribution Uplink. Every time you hit an enemy, you gain 15% Toughness damage reduction and 7.5% Toughness over 3 seconds. Progressive Plating Matrix grants 2.5% Toughness damage reduction per stack, up to 6 stacks, once per Attack. Use your melee weapon and Chordclaw Strike in between attacks.

Galvanized Coating 

Galvanized Coating makes you immune to stun effects and grants a flat 15% damage resistance. Just be careful not to get hit in melee.

Binary Ballistics Protocol

Binary Ballistics Protocol Elite kills restore 15% Toughness over 3 seconds.

Residual Current Buffer 

Residual Current Buffer Grants 20% damage reduction at 5 Charges. 

Voltaic Restoration

Voltaic Restoration Restores 20% Toughness for you and your teammates. 

Surge‑Extension

Surge-Extension On gaining a Redline Charge, you replenish 25% Toughness over 5 seconds.

"May the Machine God watch over you."
