Incase you would happen to fall in to the pond, while wearing a set you can use spells to get, it's not really a big deal.
BUT, if you fall in, and lose perhaps the dotd set or something, now that's a big deal, cuz' you can only get them like once a year, but I have a great solution to that! See, there's this weird laggthing with the TEF window, it can't minimize! So if you would happen to lose your set, just minimize the window, and the game will freeze up and an error message will follow that, and that way, your computer can't save the spelldata changes, and your set will be back when you open up TEF next time, it works for me, I do it all the time!

(Now, I can't promise it'll work 10/10 times, but it HAS worked for me, EVERY TIME! And for others who's tried this, try it at your own risk!) (:
