Many of the basic items adventurers might find while travelling in
Phantasy Star III are pictured in the game's manual. The Escapipe is an ocarina that is used to play a short musical tune capable of quickly transporting one out of a dungeon. They have a very limited range of teleportation, but it is always a good idea to carry an Escapipe when venturing into a new cave or tunnel. It provides an avenue of escape if you find yourself in over your head.
Phantasy Star III has a rather infamous game breaking bug associated with the Escapipe, as well.
