The main issue you may be reading this solution is because unlike previous quest givers (read: Favors) this is quest is not given to you by an inmate. At the utmost northern edge of the map there will be train car looking rooms. In the relative center of the map will be a train car room with an mustached NPC Magician (names are random in the game). He will have a green exclamation point that tells you he has a quest for you. In order to complete the achievement you'll need to have at least Intellect +40.
Go up to him and activate the quest (accept it). You will have to complete ALL 3 quests he gives you in order to unlock the achievement.
The first task he will give you is to locate and destroy his bed dummy. Go to the marked location on the map for the dummy, take it and then flush it down a toilet to destroy it. Once completed you will then have to go to him again for a second quest.
The 2nd quest he will give you is to craft a fake wall block. Head to the marked locations on the map to obtain the 2 Paper Maches and 1 Ink then craft the Fake Wall Block.
The 3rd quest he will give you is to craft a baseball bat and then subsequently use that bat to beat up a random guard. Go to the marked locations to obtain the 2 timbers and 1 duct tape and craft the baseball bat. Try to wait for the guard that you are targeting to be alone in an interior area. If you're outside and try to fight the guard you can potentially get sniped to death before you beat him up. Once the guard falls to the ground beaten up, your achievement will unlock. POP!
