I've been cutting through it on my Psycho. Straight Mania build with all remaining points going into Hellborn. The results are devastating. What I found from playing Gaige to level 58 is that I relied far too much on Deathtrap. No matter how I built her, I couldn't make Gaige herself strong enough to stand up to UVHM that reliably, and Deathtrap's usual tankiness wore off when the enemies got a lot stronger. I kind of attribute that to my gear now, but I've been enjoying Krieg so much that I don't wanna go back. Here's what I'd recommend though, try farming out a good Unkempt Harold from Savage Lee in Three Horns Divide, preferably a "double penetrating" variant on the higher end of the damage scale. If you combine that with a full load of anarchy stacks I'd be willing to bet your problems will disappear.

Do every side quest you can

Slag everything.

I reset my lvl 61 zerker and have been just stomping threw the whole thing

You will get wrecked if you dont have atleast 3 of these 1slag weapon -easy to get-mandatory 2 the bee - moderate to get - mandatory 3* sand hawk- requires dlc- highly recommend 4the sham -farm bunker - very rare 5 norfleet -very very rare- 6 friends to play with 7 infinite pistol - you may die of age before u get it 8 double penetrating unkempt herald -requires dlc 9 grog-nozzle dlc easy to get -mandatory 10 magic missile dlc -very important 1[b]1 lascaux - a smg it is very easy to get and i would recommend getting one every 2 or so levels it is not mandatory but at lower levels very helpful [/b] If u r on xbox one ignore requires dlc For gage i like an anarchy build Also almost every one of these items has a specific method to obtain them google it for more info on the subject Side note u will struggle immensely if u lack these items my advice is look for a friend who has them to help u get to max level and then proceed to have him dupe u the items or farm for them urself also u may want to obtain some of them before max level just to make the process less stressful and then get them again once u r max level *= this item is NOT obtained multiple times on the same playthrough The best legit way to earn these is to look for a video telling you how to get them and then farm for hours The best way if u dont care about legitness is to ask someone to duplicate their items and give them to u Good luck If u ever r confused or need help with explanations or even just recommendations on how to beat a boss ask me
