Test Support build
 Zealot Build - Warhammer 40k: Darktide 

This is a test build, trying a full melee support build, it has insane cooldown from 2 sources, "Martyr's Purpose" and "Invocation of Death"

the weapons and perks are personal choice, i just put the weapons i prefer (the stub revolver or the headhunter autogun are also good choices to help take care of elites/snipers that keep their distance)

the relics are also personal choice, i tend to like cooldown reduction and Combat ability regeneration, as the goal is to use Chorus of Spiritual Fortitude as often as possible

i tend to use Immolation grenade as it can clear hordes with ease and stop dogs from pouncing allies when hunting ground is active
 

AGAIN, THIS IS JUST A TEST BUILD for a pure support Zealot

EDIT: remove Holy Revenant and Until death (and the passives leading to it) 
added Disdain, Enemies Within Enemies Without, and Bleed for the Emperor
provides more self sustain

EDIT2: removed Fortitude of Fellowship, Added Faiths Fortitude (works better with Bleed the Emperor)
(gonna be testing a few more changes and maybe adding more)
