The Trainer's Whip is the second of three Class-Changing Items acquired in The Lost Age, and is found in the Yampi Desert, shortly after defeating the King Scorpion. When you reach the three sand rivers, climb to the top of them and go to the far right river. The treasure chest contains the Trainer's Whip, which changes the character class to Tamer, and opens up a completely new set of Psynergies, all but few that change each time you upgrade the class with the whip equipped. Being acquired at a time when Djinn distribution is still a little uneven, it is a great addition to the team, and thus eliminating the changes of two characters' classes, regardless of what Djinn they possess, allowing the third to possess a more stable class. If sold, it can be bought for 666 coins.
