Easy Leveling XP
When you complete the quest 'A Dam Fine Rescue' and return to Sanctuary Sir Hammerlock will offer you a quest called, 'Mighty Morphin''. This quest involves taking an Injector and injecting Varkid Cocoons with a special serum that creates a large flying Badass version of a Varkid. Killing one yields 1,900 Experience. Providing you do not complete or turn-in the quest you can kill ALL the cocoons in this area, save the game, reload, and repeat as many times as desired.
