Chainsword Attack Speed Arbites
 Arbites Build - Warhammer 40k: Darktide 

In Theory : 

• Hammer of Judgement + Targets Acquired + Lone Wolf gives a total of 30% attack speed when swinging into hordes. 
• Cadia Mk XIIIg Assault Chainsword has excellent Light Attack spam when paired with a good amount of attack speed. Effective against hordes and Maulers.
• Very good against hordes that are mildly mixed in with Flak armor, but when dealing with packs of Crushers and Ragers, knock down as many as you can with Break the Line and toss down a Voltaic Shock Mine (which recharges due to Lone Wolf) to kill enemies one by one with Special Heavy Attacks.

Notes :

• Lone Wolf is great for grenade spamming. And with this build lacking a bit of lethality against Crushers, this is your most reliable way of dealing with them when they come in great numbers.
  • That being said, you can totally just bring a Locke Mk IIb Spearhead Boltgun instead.
• Judicial Force is a weird one. Still have to test it but it does knock most human-sized enemies on their butt whenever this triggers. If you personally don't find value out of it, reallocate that point somewhere else.
• You can also reallocate the point spent in Rapid Movement into somewhere else. 
  • Maybe into Soulguilt Scan, Ammo Belt, or a +10% Melee Damage node.
• I've played with this build for several games in Auric Damnation and it holds up pretty well. It really only gets in trouble when you're in Scab Only Maelstrom and packs of Crushers/Scab Ragers will come at you faster than you can regenerate your Shock Mines. Hopefully, you'll have teammates that can also deal with that while you're out of mines.
