Magic pots are probably the best enemies to use for the "Super W-Item Trick". And you will always receive a turbo ether, 8000 EXP, 1000 AP and 8500 GIL from Magic Pots.
Absolutely. Once you learn of the W-Item duplicate item trick, Magic Pots go from being at the top of your "Most Hated Enemy" list to the top of your "Most Loved Enemy" list, right next to the Mover.
