No One Better Achievement
No One Better50
Bring any character to level 50Completing the story and every side-quest, as well as grinding to max out your weapons and armor, will only get you to about Level 43 (or at leas that's what I was at the time). The final few levels can easily be done defeating the boss in the lava area a few times on Hard difficulty. Exit back to town to respawn the boss and repeat.
