Made from the same stuff as a Dewdrop Pebble.
The Levistone (浮遊石, Fuyūseki?, lit. Floating Stone), also known as Floater Stone and Pumice Stone, is a recurring item in the series.
Mysterious rock that floats in the air.
The Levistone is a key item found in the Cavern of Ice, guarded by the Evil Eye. With the Levistone in their possession, the party can travel to the Ryukahn Desert, at which point an event is activated automatically (the key item has to be selected in the NES and Origins releases) as the Airship rises from the sands. The party can use the Airship from here on.
The Levistone was used again to raise another Airship while venturing through the Hellfire Chasm.
The Levistone makes an appearance as a Trade Accessory.
Levi is short for Levitation. Levitation (from Latin levitas "lightness") is the process by which an object is held aloft, without mechanical support, in a stable position. Levitation is accomplished by providing an upward force that counteracts the pull of gravity (in relation to gravity on earth), plus a smaller stabilizing force that pushes the object toward a home position whenever it is a small distance away from that home position.
