Easy way to get infinite Elixir

This is the fast and best way to get you infinite itens but it uses a glitch with the W-item materia, so you gonna need it

1: Equip W-iten in someone of your party (must be W-item, not master command)
2: Chose the W-item option and select Elixir and use in someone
3: The second item you chose once then don't chose in who you should use, just press cancel, this will make the first item chosen add one more
4: Repeat the method how many times you want with any usable item (in battle)

I use this method to get infinite Elixirs and give to Maic Pots in North Cave and farm tons of AP, for those who want the materia overload achievment.

I hope I helped all of you!
Any question how to make this feel free to add me and ask.
