A great item called the Magic Lamp is hidden away in the world of FFV. The location of the Magic Lamp is as follows: Once the two worlds have melded together, hop on your Yellow Chocobo and head toward Easterly Falls. Ride the Chocobo through the narrow river to reach the top of the falls. Enter, and press the X button to obtain the Magic Lamp!

The Magic Lamp calls upon random Summons during battle, and you can use it over and over! However, each Summon can only be summoned once, except Chocobo, which will end up being the ONLY Summon you can call upon. But do not fear! There is a way to "refresh" the Magic Lamp so that you can call upon each Summon once again!

Once you have the Submarine, head toward the Dwarf Village. Inside the village, there is a spring (B7). In the bottom-right hand corner of the spring, there is a gap which appears to be a passageway, but not quite. Enter the gap and the screen will flash. There, now the Magic Lamp has been refreshed! You can return here at any time to refresh the lamp.
