I personally don’t feel it’s that needed since it’s pretty easy to get a grenade kill on a little red bar enemy to proc it. That way you also get volatile rounds. Higher difficulty content makes it harder to proc devour since ads are tankier, but scatter grenades still don’t usually have a problem killing rank and file enemies even at those difficulties (scatter grenades are my go-to since they lowered its cooldown and extended vortex grenade cooldown
