The Lucifer Black - Stealth Shock Build
 Veteran Build - Warhammer 40k: Darktide 

The Royal Executioner Build - "Emperor protect my soul, flak protect the rest"

A member of Terra's own Praetorian guard regiments, entrusted with a duty no other regiment is given: standing between the High Lords and everything that wants them dead.

• Palace Power Glaive (Achlys Mk VI Power Sword) -  A premier horde clearer with lights when energised and a solid armour dealer through its push stab, which has stupid finesse damage only amplified through Desperado, Precision Strikes and Rending Strikes. The Poor mobility is somewhat offset by Duck and Dive but still remain careful with the limited dodges. Even the Emperor's finest need breathing room before the real work starts.
• Night Watch Pattern Bolter (Locke Mk IIb Spearhead Boltgun) -  This mark is meant to be used up close and personal with these blessings. Dealing death into packs of elites, or bosses, with Puncture and Cavalcade for maximum impact, not for single shots at long distance. use to deal with specials with One Motion. however ensure you have a full clip ready with Lock and Load to use used with Infiltrate. 
• The Black Vigil Stance (Infiltrate) -  This ability is used to get close to threats with your rather slow weapons and for objectives and revives. Can keep one spare for an emergency thanks to Overwatch. When faced with a mortis-level threat, gameplay looks like this: go stealth to stack damage from Close Quarters Killzone Marksman and Infiltrate itself, tag to Focus Target! on a boss or overwhelming horde, then mag dump with your bolter, aiming for weak spots. We work in the dark to serve the lords of Terra after all...
• Shredders (Shredder Frag Grenade) -  While not the most powerful, can be tossed quickly and not break stealth if thrown underhanded, very good to mix into a horde about to hit your team before you get to boltering. 
• Terran Death Order (Focus Target!) - Perfect addition to your Bolter to burn down bosses or to mix into your melee fights to keep stacks of Redirect Fire! high! We are the bodyguards of the High Lords! So give direction to the team like a true commander!

WARNING — You’re no Zealot with Infiltrate, and the Vigil doesn’t ask you to be. It asks you to stay close and strike the moment the squad needs it. Keep to the team!
