Easy Legendaries
Although this is not my way of playing I would like to inform you that there is an easy way to farm legendary weapons in the Claptastic Voyage. With Borderlands 2 there was such a thing as the moonshot trick. When killing the final boss for the first time you would get a guaranteed legendary drop. By saving the game just before the final moonshot you could reload your game and farm the Warrior without having to kill him over and over again.
This method is also possible during the final boss of the Claptastic Voyage, and because EOS drops (almost) every new legendary weapon, it is a fast way to farm for them. You do this by forcing the game to save just before retrieving the H-Source.
You can do this by turning off & on your badass rank in the menu. Now you can dashboard (console) / ALT+F4 (PC) your game to start at this point in the playthrough. Get a buddy or mule (second controller) to join you and start farming EOS. While the second player gets the loot, he needs to Save & Quit, you need to force close the game by dashboarding on console or ALT+F4 on PC.
An advanced trick for PC is that you can set your save file to read-only. This prevents the game from overwriting your save data and gives you the ability to also use Save & Quit (don’t forget to turn it back to active when you’re done).
