Unfortunately it isn't, haven't played Gotta Protectors in four days or so. Been busy with work and other games, but I plan on hopping back in soon. If you type in "Gotta Protectors GameFAQS" and in the first link go to FAQs/Walkthroughs there seems to be a pretty in-depth ring maker guide already made. You should check it out. I heard Japanese players have even more guides on the game.
