Dragon Mania Legends

This is another achievement that will likely come naturally, as you will need many different types of dragon for the different fights. However, you can get this right from the start, and actually make a little profit!. Each fire dragon costs 100 coins, and if you buy it and pet it three times, you will make 20 gold per pet. Then sell it for 50 coins, and you are 10 coins in profit!
