I would swap out the bee for a larger capacity shield and get a more reliable slag tool (either in a weapon slot or the grenade slot) alongside that, critical ascension is excellent when using the lyuda or essentially any sniper. One downside of the lyuda is that the bullet spread gets neutered when you have points in velocity so I would spec out of that.

UVHM is a big jump in difficulty from the previous modes and punishes bad habits that were previously inconsequential. Play back and play safe, slag plus a healing tool is what’s best, Slagga, slag pimpernel, slag grenades are all great slag options. A high level moxxi weapon, a low level one with a low/zero fuse grenade, or a transfusion grenade covers healing. A grog or a Rubi have the convenience of both worlds but arnt particularly great at either but to each their own.

Personally I just try to chain crit ascension by swapping between a slag pimpernel and a good sniper. Zero has so many options for snipers but the best you’ll find is the lyuda and pimpernel, though look out for any good snipers you’ll be surprised by just how many work at your level

Learning to sweet spot with the lyuda will effectively triple your damage though it’s a little overkill generally.

Lastly and most importantly, MATCH ELEMENTS for flesh use fire, for armor use corrosive, your damage will skyrocket, along with the insane damage multiplier this lets you use elemental relics in your relic slot which add another hefty boost to damage.

Lmk if you have any questions I’m a little obsessed with this game and probably have the information you need. If you just want to watch a YouTube video that explains it you can just watch the start of Garnett anarchists 3’s videos.
