Cakey's Bladey
 Zealot Build - Warhammer 40k: Darktide 

Munitorum Mk X Relic Blade:

Energy Leakage + Rampage were picked because they're the only blessings giving you both damage and cleave (even though it says damage on Rampage, in actuality it gives you strength because FatShark bed england). Without them both you'll have hard time cleaving through enemies majority of the time outside of Weapon Special mode.

For empty perk you can choose between Maniac or Unyielding.

Munitorum Mk II Relic Blade:

Even though Overload + Heatsink don't have any damage related properties, paired together they're allowing you to stay in Weapon Special power state longer and cool it down much faster even in comparison to Overload + Cranial Grounding. Heatsink works both while in Weapon Special and while it's on cooldown.

For empty perk I recommend picking Maniac damage.

Artemia Mk III Purgation Flamer:

It's pretty much infinite, no need to reload, unless not in Blazing Piety+ Righteous Warrior.
To whip it out faster, right after swapping to Flamer press blitz to throw Blades of Faith. It will skip big chunk of Flamer's taking out animation by rewriting it with own throwing animation, which is way faster.


Feel free swapping between Unfaltering and Thy Wrath be Swift.

Unfaltering removes any action movement speed penalty, makes windup animations of weapons uninterruptible so they cannot be canceled by hits and grants immunity to stuns and slowdowns from both melee and ranged attacks. Personally, I find it most useful on Munitorum Mk X Relic Blade, since it hits the hardest with heavy attacks and relies on them more than Mk II variant.

Thy Wrath be Swift is pretty similar.
It always grants immunity to stuns and slowdowns from both melee and ranged attacks (never trust in-game FatShark's descriptions) and for 2 seconds after taking damage to toughness or health by any attack, increases movement speed by 15%. I usually pair it with Munitorum Mk II Relic Blade, since it feels a bit more faster in terms of handling in comparison to it's other mark.

Same goes with Risen. If you're having hard time keeping high toughness, try switching Risen to Enemies Within, Enemies Without, if it doesn't help you...
... skill issue ¯\_(ツ)_/¯
