First, take some booze if you want to be sure. If you want to do it in Arroyo, so you'll have no booze, but some healing powder should do just fine. So get an item, like your spear, implant it on somebody. Then, steal it. Doing this you'll get 20 xp, and you can do this as much as you want to. So doing this for like, 50 times, you'll get a level
not cool huh? Well I just thought you should know
