Just for reference...

Riddle: Why would I buy this item that I see?
If you were smart, then you would agree!
It's so much worse, I guarantee!
Wanna know why? Just ask the three...

Hints: You can buy the item, last line refers to "third" (hehe), three refers to something stronger than the answer, cannot be used with the item command

Wrong answers: 3 batteries, broke vending machine, potions, tranquilizers, tents, curse ring, chocobo stables, W-item glitch, Jesse/Wedge/Biggs, chocobo lure, enemy lure, bronze bangle, hyper, aurora rod, organics, parasol

Is it the Quake or Quake2 materia? Since there is also a Quake3. It can also be purchased in a shop.
