Yeah it's a fukking grind for the opulent weapons and the haunted weapons... all I have left for red bars is 2 of the shotguns and then the fukking duality weapons
The trace rifle once you level it up with Enhanced Killing Tally and Enhanced Lead from Gold is vicious
You don't have to grind like that. Just get the upgrade that guarantees one Opulent Deepsight weapon a week and then use all the Umbral engrams you have to get a random Opulant weapon. about every 3rd or 4th umbral I pop turns into a deepsight weapon and the game throws umbrals at you. my biggest issue now is having the umbral energy to gett the weapons.
