Raise your level really easily without risking your health

In Athens, go to any of the places where you can buy a hotel. Then go to the guide. Click "I want to know how to play this game." Then the guide will say something, and click "I prefer doing tasks". She'll then give you a mission. The mission is go kill a leet. Go into the training grounds and kill a leet. Look at how much xp you get, 537 or something or other. Then it's go kill three leets and you get a bunch of xp again. Then the easiest of them all, go find the Second Hand Peddler. Guess how much you get? 1000xp and then a side bonus of like 500. Keep doing it and you'll level up easily. And there you go.
