Adora's 'Havoc Benediction' Chorus Duelling Sword
 Zealot Build - Warhammer 40k: Darktide 

A build for if you're lucky enough to already have a Zealot running Beacon of Purity. This build is basically a 'perfect quality' set up. Health regen, high base damage, high DR, and Immolation Grenades for when things get hectic. Use the Boltgun on snipers/monstrosities, Duelling sword for everything else. Keeps you alive pretty well and gives the team desperately needed DR. Though if the other zealot isn't using a flamer, it's likely better to put that on, but I have that on my purity set up so I decided a Boltgun would be nice. 

Otherwise, the game plan is simply to dodge a lot, hit a lot (through light/heavy attacks into pokes to animation cancel), and chorus as much as you can to keep everyone alive and all the enemies from overwhelming the team. Rinse repeat until victory, with the capability of taking a few hits along the way thanks to being a zealot.
