[2.0] If Leonardo was a toaster and cowboy character from hero shooter Overwatch named McCree but without flash grenades and then was renamed to Cassidy for mysterious reasons and also keep forgetting to say his famous line "It's high goon"
 Skitarii Build - Warhammer 40k: Darktide 

Fanning Revolver combinations:


[1]
Perks:
+25% Damage against Carapace
+10% Reload Speed (This way we'll get full bonus from Piercing Sight right for all next shots after reloading. Any more additional reload speed might cause first shot to not benefit from full Piercing Sight bonus)

Blessings:
Point Blank (fits well with general playstyle of this build + works on all 5 shots in fanning, to the time of reloading next 5 rounds, it's effect will diminish and gets replaced by full Piercing Sight bonus. We only lose 5% crit chance from replacing Point Blank with Piercing Sight this way)
Sustained Fire (in combination with Rad-Sink, Sustained Fire makes 90% of our shots to always have 20% Strength bonus)


[2]
Perks:
+25% Damage against Carapace
+5% Crit Chance (instead we're taking Gunsmith, risking our first shot on next reload to not benefit from full Piercing Sight buff because reload's faster than 4s requirement, but we gain an option to unload 2nd fanning very quickly thanks to unintended mechanic that derives from a bug from this talent which affects staged reload animations in a weird way)

Blessings:
Point Blank (fits well with general playstyle of this build + works on all 5 shots in fanning, to the time of reloading next 5 rounds, it's effect will diminish and gets replaced by full Piercing Sight bonus. We only lose 5% crit chance from replacing Point Blank with Piercing Sight this way)
Hand-Cannon

I prefer [2]nd option because it kills Crushers faster.


Talents optimization:


Swap talent Flux Conduit Build-Up/Augmented Power-Cycle/Reactor Coil Recharge to Last Stand Relay depending on what you're lacking
Can't have consistent 5 Redline Capacitors stacks?
    Take Flux Conduit Build-Up/Augmented Power-Cycle/Reactor Coil Recharge
Feeling in need of additional crit?
     Take Last Stand Relay

Swap Augmented Power-Cycle, Flux Conduit Build-Up and Reactor Coil Recharge around depending on which of them makes you regenerate Capacitance more frequent and faster


Blitzes:

Noospheric Command too far away and we simply don't have talent points + risking on overusing it and dropping Capacitance stacks too much, especially without 2nd Capacitance recharge talent (Flux Conduit Build-Up or Augmented Power-Cycle), which interfere with constantly keeping 5 stacks of Redline Capacitors and Advanced Power Management intact

Arc Grenades are even further than Servo-Skull upgrades and also are extremely positional and situational. On difficulties Damnation and lower often not enough enemies to make arc chain lightning explosion to deal massive damage, not to mention that this is an overkill. On difficulties Auric and higher too much enemies can cause diminishing returns because of how they work (watch Ryken's XIV video "Darktide Just BROKE The Golden Rule of Chain Lightning!" about them if you're curious). Proper positioning of yourself and enemies are required to avoid diminishing returns

Integrated Refraction Emitter is very niche and works mostly in dodge related builds because technically it applies dodge state against ranged attacks and can be put together with Desperado and other dodge related stuff, which isn't our case. The only dodge related things we have are Precision Combat Augurs and Riposte. Last one will consistently work by itself thanks to lengthiness of it's effect. In the span of 4 seconds we eventually will successfully dodge incoming attack, refreshing this Blessing. Take out whatever talent you're not comfortable with and pick this blitz if you want


How to Redline Capacitors and Reactor Coil Recharge:

Quickly turning on and off Advanced Combat Doctrines will give you one stack because 5 full Capacitance will drop to 4 full and 75% charging, and Augmented Power-Cycle with Flux Conduit Build-Up will regenerate 5th stack back very quickly, rewarding you with another stack. Keep doing this whenever you're starting to run out of these buffs to keep all 5 stacks and other related buffs like Sequenced Charge and Moebian Conductor active all the time
