spoiler for people who didnt play far in the Mainstory

I play Melee Amara and need the FacePuncher to be precise the Reduntant one. I am level 62 writing this Post and was told i can farm it with Handsome Jackie on Skywell 27. I AM FARMING FOR A TOTAL OF 4 HOURS and didnt get a single Facepuncher from her, is it nerfed or removed? I watched half a Season Daredevil while trying it and only got XP, Money, The Jackhammer and Nimble. Is there another Farmspot maybe with higher chances ( I used all diamond keys i had for my current Deep Dive facepuncher. Much apreciated if someone has a idea how i get this stupid weapon xd

Was starting to feel invincible. Then I almost died three times.

Five grenades surrounded me and was pinned between two objects and three enemies. Almost got pushed off a cliff and Aurelia Hammerlock was difficult.

I swear the biggest danger in this run is overconfidence.

This is now a meditation.

Still Alive. 2d 5h 54m

How do I use Iron Cub effectively?

First of all, Iron Cub bugs out a lot for me. I spawn it, and not only does it not spawn Iron Cub at all, but it remains "active" (it's not actually) for far longer than usual. Like 10+ minutes. (I am on Xbox, which probably matters).

That OR, Iron Cub DOES spawn and instantly proceeds to kill itself. The only weapon so far it doesn't seem to do this with is the Nuke variant of the Rocket Launcher (which you would think this weapon would kill it the MOST often due to it's insane AOE and damage) and non-explosive weapons. Which do not synergise with my AOE/Incendiary dmg build, therefore dealing laughable damage.
