Although some people may class this as cheating because of the name, in fact, it is completely the opposite! You can get full stats on strength, defense, magic, dexterity, and vitality without even cheating, but it can take awhile to do.

REQUIREMENTS

To get unlimited sources you require the Morph Command Materia.

LET'S GET POWERFUL!

This one can be tricky depending on who you go and Morph, but the best place to gain Power, Magic, and Guard Sources is in the Sunken Gelnika. However there are other monsters which you can Morph into different sources.

Now that you have the Morph command materia, you should also have Yuffie (one her very few uses in the game) since with none of her weapons become weak when trying to morph something. Once you have that you can fight the following enemies for certain sources (please note that only the best results are listed), instead of killing them normally, the killing blow must be with the Morph command.
