Could just be that I'm playing it wrong though
here are my skill points
I'm using a legendary reaper COM, the peak opener, the hard carry, the easy mode, a corrosive/shock fastball, the grog, a corrosive topnea, and a slag conference call. In my backpack I have a flakker, slagga, DPUH, storm front, and a corrosive pimpernel.
My issue is that even if I do kill dukino's mom, I'm usually out of ammo on all my weapons even though I have max SDUs because she takes forever to kill. I usually make sure to have bloodbath active when she spawns. I made sure my gear is on level and I may have to take points away from fire fiend and flame flare and put them into pain is power because enemies in the peak are neutral to fire
I don't really have a strategy for dukino's mom yet either so I have no clue what I'm doing in that fight
