After reading the patch notes I decide to hunker down and try to get two wicked relics before they get MUCH harder and tedious to obtain. Several hours later, I did it an I feel like a madman. I am not envious of people who will have to get the bus without a time out gum. I think you can still use the trap to kill the crawlers on a ammo round, but if you get hit even once then I imagine that is going to hurt at round 60+
To everyone still trying to complete these after 12/4… God help you. Best of luck
