Price's 'Swift Ironhelm' Martyr Chorus
 Zealot Build - Warhammer 40k: Darktide 

Same concept behind this as Adora's Evis variant, this was created with the idea of 'making a Ad clear hammer build that uses Thy Wrath Be Swift'. It functions rather well, not as ability heavy due to needing to use Martyr's Purpose (though you could forgo attack speed for backstabs, but I didn't think that would happen that often either), but you still get the chorus'es when you need them, and otherwise just spam heavies into the wave and knock everything over, while continually gaining a good bit of toughness every kill, and being unstunnable (which greatly helps the thunderhammer). 

Revolver for pot shotting long range targets and dropping armor when needed, since the ironhelm doesn't do nearly as well against that. Stun Grenade for when you need chorus but it isn't up yet, and you don't want to/don't heave the health to wait for it to come back. (revolver also becomes pin point accurate while hip firing with Dance of Death, so that's nice).
