Okay I know a lot of people know how to do this but since a lot of people still are asking for help with their sets, I'm putting this out so I can help out others who don't know this awesome trick ^^

1. Open the game
2. Open menu
3. Click Display and check "Run in a Window"
4. Close the game.
5. Open it again. Your game should be in a window.
6. Open another game.
7. Now you can give yourself the spells ^^

Ta Da!

Although I have a warning, this will not work on all computers, as I have learned. I have two computers, one of them can't run in a window, the other can though. If it helps, I can run the game Windowed on a Sony Vaio Windows Seven, it won't work on my Dell Windows XP.

(I remember when I found this trick out, and I was such a n00b before XD)
