Poketide (Loner)
 Zealot Build - Warhammer 40k: Darktide 

Giving Dueling Sword to Zealot was a mistake. Here's how you can abuse it.

You have INFINITE DODGES, so use them to your fullest advantage. Keep those dodge buffs active as much as possible. Sliding will be necessary for ranged enemies, make sure to angle up to hit the head while still in melee combat.

When dealing with small groups of heavy armor (around 3 crushers/maulers), just use your dueling sword. Fury of the Faithful does great damage vs armor, so aim for the head. Heavies only for single-target, use light attack spam vs crowds. Special attack is a good interrupt vs ogryns/mutants.

Because of your aura, I encourage you to run ahead of your team and split off often to deal with pesky ranged enemies and the occasional special. Don't forget to stick by them when need be, e.g. boss or horde. Martyrdom is insurance and makes you lower priority for healing - if you don't want to use Martyrdom, you can drop those four points and go into right Blazing Piety + take Thy Wrath Be Swift. Leave Faithful Frenzy. Get good with throwing knives, snipe specials with them.

Flamer is for big, BIG groups of enemies, or lots of armored elites. You'll want to conserve your ammo for your teammates. If you are not sure you can reliably deal with a horde, flamer is a good insurance option. Always magdump the whole thing when dealing with ogryns. Don't use it vs bosses, just poke them with your sword.

Have fun!
