If you know a mage friend, and if you have preferably a 100% mount both of you (or 60% with carrot on stick), then you are set to go. Go to the bank spot where you can duel, and duel. After that, go east and in the corridor, then, as fast as possible run and cut corners and get to the king in IF. (I usually run to the left side of the room and and I make it with 1sec left until forfeit :P) So, what you do then is that the mage and you are still in the duel, and you run up to the door witch you see on the right side. (Left side is only a empty room). Then while you run and keep running towards the mage sheeps you. If you are lucky the sheep will walk trough the door and inside the Old IF corridor. If not, retry.
Here are some screens to help you out:
Start the duel here ..
If you are lucky, you will make it and you will get into Old IF if the sheep walks inside the door. GL
