How do you get luck cannon in tvhm?

I read a few guides that say ultimate badass glitches but i’d like one around lvl 44~50 for my uvhm playthrough. would grinding be the best for it? i cant seem to get ultimate badass glitches to spawn in tvhm.

I thought the luck cannon came from EOS at the end of the claptrap dlc. I think the flayer is the gun that could drop from the glitches.

both the videos i found on it said the same thing they come from ultimate badass glitches, the borderlands wiki says adbots so i have no idea i just want one :frowning:
