 Zealot Build - Warhammer 40k: Darktide 

                                    -- - Want to spam a book every 10 secs and give your team never ending gold toughness? Then this is your build. - --

     To start off how does this build work? Well it's not too complex however it's a different kind of playstyle then how you normally play the game. When it comes to Chorus of Spiritual Fortitude spam builds you want to pair them with Pious Cut-Throat and Invocation of Death along with the keystone Blazing Piety and Righteous Warrior with this combo you'll on average have a crit rate of 50% which means you'll almost always have 200% cooldown regeneration along with a very massive 20% ability cooldown on backstab. You can also pair this with a ability stim which also pairs well with Invocation of Death which brings it up to 300% Cooldown on top of the already faster cooldown from the stim. However you don't fully need the stim and are better giving it to the Voice of Command vet if you have one in the comp. This should bring your book back on average 5 - 10 seconds. 

     Why Catachan Mk VI Combat Blade and Accatran Mk XII Recon Lasgun I hear you asking. For knife it helps a ton when it comes to getting those backstabs and coming back to the team also the push attack is great for landing those backstabs. Why not Catachan Mk III Combat Blade that's due to the much better push attack the Mk6 gives you which with this build you'll be using alot. Recon might seem a odd pick but trust me it just works. You'll be using this to deal with Snipers or other specials your throwing knife cant get to. Also helps when it comes to gunner lines that you cant push into due to not having book at that moment or not wanting to trigger a boss or ritual. If your using your recon correctly you won't be needing ammo all game even without a Survivalist vet just make sure you let the Infernus do it's job.

     You will not be the damage dealer of the team and more akin to a support role. Whenever your fighting a horde or boss(es) you should always be looking to get backstabs if possible so your book is off cooldown. Make sure when your team is fighting a boss book it into a wall so your team isn't chasing after it trying to deal damage. You should also set it up so the head isn't clipping into the wall this is only a problem with the Plague Ogryn the Chaos Spawn will turn around fast enough so it's never a issue on them. Beast of Nurgle can't not be staggered so nothing you can do with them.

     Some advanced tips I can give is when it comes to bosses or a bad ritual spot if there's a ledge then send that thing to the shadow realm with your book. Also, when fighting twins save the book till their shields pop. For whatever reason book messes with them and they wont pop instead staying at 1 hp. If you do book to soon you need to get them out of the book stagger radius so the shields don't bug. Loyal Protector is you best friend since it makes for super easy backstab.

     As always curios are up to you there's no right or wrong there just make sure you bring the ability cooldown regeneration.

                                                                                                                       Best of luck future book club CEOS
