Ethereal Monsters

Ethereal Monsters are a new class of monster added to the game on June 14th 2013. They behave in many respects like a five-element monster, but each monster has its own unique element.

With the Anniversary update, Ethereal Monsters can now be fed up to level 15, at which time they can be placed on Ethereal Island, instead of Gold Island.

Feeding Monsters
Each monster needs to be fed four times before it reaches the next level. Increasing the monster's level increases the coins earned per minute, as well as the maximum coins earned. The food for each level is the same for each Ethereal monster.

It takes 1,310,640 food to get an Ethereal Monster from level 1 to 15.
