Fallout New Vegas: how to earn XP fast
Gain experience without much effort in Fallout New Vegas
Do you need to quickly level up your character in Fallout New Vegas? Here is a little help for you.
If your "Persuasion" skill is 50 or higher you can convince Old Ben to escort you to the bar. Succeeding in this will earn 61 XP. After that, if you follow him back to the bar and wait for him to sit down, you can talk to him again and repeat the same Speech Challenge to earn another 61 XP. Repeat as many times as you like to accumulate a lot of XP.
Old Ben is found sitting by a fire in The King Headquarters in Freeside.
