At around level 40, go and do a random adventure. If you're lucky, you will enconter a legendary warrior. After you beat him, go on another random adventure, and you might have his sword in your hands! (This seems to be random though I'm sure something triggers it). Now, go into your weapon equipment, and you will see a bunch of scrambled text under all your regular swords. Click on a regular sword that isn't bugged, and then click onthe scrambeled text. When you see "LOADING", things get weird. You come in as just a sword, and the sword is the guardian blade. Hit attack, and the screen will go atari-style and the game will lock up.
