Zealot Hi Octane
 Zealot Build - Warhammer 40k: Darktide 

Yours role is to eliminate enemies who are in front. 
You can sneak behind them using invisibility and quick movement to the enemy's rear. By eliminating enemies with a high chance of critical hits, you quickly regain your ultimate ability. 

Invisibility also restores toughness, so you can treat this ability as a "jail-free card."

The revolver allows you to eliminate elites and specials. With the blessing of a handcannon and "surgical" precision, you can take down a Crusher in 2-3 weak spot hits. 

>>>The build is very versatile, but you shouldn't play alone. Your role is to be the vanguard, precisely and surgically removing threats and returning to the team. <<<

Bleeding on the knife allows you to stack damage to later trigger rending, increasing damage from bleeding. Attacking the horde 2-3 times while constantly evading, your enemies will soon bleed out.

This build is applied at the Auric level.
