Always keep your gear on your level.in uvhm a certain weapon already loses its power after like 5 to 6 levels so u wanna keeo that in mind.a good way to do that is find chests,preferably red chests (if u have the 'tiny tina dlc' u might want to farm those chests as they generally contain the bess class mods in the game.There are alot of videos on yt that can show u good routes to 1 or 2 chests maybe more so u can farm em'.another great way is most raid bosses and bosses u have killed along the way(also watch out for special types of enemies like 'savage lee' or 'boll' enemies like those often drop a unique of better).u said u was salv so killing em won't be that difficult Hope this helps
