Borderlands 2: Hero's Pass/Vault Of The Warrior 2 Chest Farming Run

 After working through Hero's Pass there is a quick 2 chest farm that can give you some upgraded gear before taking on the warrior. After entering the vault, save & quick. Go back into the game, exit out to Hero's Pass to check the chest just out the door. Enter back into the vault, & navigate to the hidden chest as depicted. Save & quick again then rinse/repeat. Note: you can't get out of the space where the hidden chest is & the lava will kill you. Average farm time is less than 1 minute so you can do quite a few runs in no time at all. Fyi, this is on PC & running the community patch V4.0 which probably explains why I got a Legendary Explosive Nasty Surprise on the first run.
