I leveled all of my Ethereals to 20 at a cost of over 1 billion food.

They pay out bonuses sometimes when they’re above 15. Ethereals paid (in addition to the shards) either 10,000 food, 1 diamond, or 1 relic. Keys may also be Amin’s the bonuses but I didn’t catch one with the last harvest. Among the 60 monsters I got 4 diamonds, 2 relics and 80,000 food. Small payouts to be sure but free is free.

Haven’t had a chance to really see the bonus stats from regular monsters but if my eyes didn’t deceive me a one element monster paid an additional 100 food on collection. I’ll pay better attention next time

The extra food item is a waste of coins as it costs twice what a cake does but only gets 1.5 times the payout over the same time span. With the high cost of leveling to 20 it can deplete your bank pretty quickly.
