Looked for something similar and found nothing, feel free to flame.
In Wizard's Sanctum (the mage tower in SW), if you walk backward through the portal that leads to the stairs, the game won't recognize your direction. It will spawn you with your back at the portal, while it should be in front of you since you were walking backward. Doing so, keep pressing the Back key, and you'll continue to enter and exit the sanctum.
Is a bit confused, since i'm not english, but tried to be as clear as possible :confused:
Pretty fun for the first 10 secs; 20 if you are really bored.
