Fastest way to boost XP. Level up to 72 - Borderlands 2

This is by far the fastest way to level up you Borderlands 2 charer. It does take a bit of preparation but once you have that done you can level from 61 to 72 in about 2 hours.\r
\r
Each load up and kill of Jack takes about 2 mins and gives about 20% of a level worth of XP to the charer being boosted. Much more if they arent the highest charer in the game.\r
\r
This will work from level 1-72.\r
\r
- Using your main profile/charer run a second profile (one with xbox live privileges if you want to boost friends online) up to the point in the game where the warrior has been killed by the moonshot but Jack is still alive, in the second profiles UVHM game.\r
- Kill yourself instead of Jack and exit the game.\r
- Back up your secondary profiles game to a memory card. (not essential but highly recommended)\r
- Load up the secondary profiles game with a charer that you want to boost also in the game. \r
- Kill jack.\r
- Sign out with the secondary profile. (Game will save for the charer that you are boosting but not for the secondary profile)\r
- Sign secondary profile back in.\r
\r
Rinse, Repeat. \r

Profit.
