Once you get two different ethereal monsters to ethereal island you can breed them. The single element monsters give a decent amount of shards at level 10, and that doesnt cost tons of food. I suggest level 10 because once you get the double element monster you may want to replace most of the singles. After getting just two different of the double element monsters they can be bred together and you always get a double element ethereal monster. Then you'll be making great shards and will be awesome in tribal island.
