User blog:AimeePlaysMSM/Should you breed dissimilar Ethereals?

My niece the other day asked "why are you still breeding the Jeeode and Rare Jeeodes together?" [on Ethereal Island]

That was a good question, which was in reference to the more recent Rarethereal event that had also long since ended. Originally I was doing so because the Rare Jeeode was available months ago, trying to get plenty of those on Ethereal Island, and just never stopped hitting 'Retry' while going over each Island in turn.

But does it make sense to do so when the Island is full and it's basically just collecting a smidgen of additional Shards? Specifically: would it make more sense to breed dissimilar Ethereals, sometimes resulting in a Two-Element Ethereal instead?

A Jeeode takes 7.5 hours to Breed (Enhanced Breeding Structure) and sells for 20 Shards.

A Sox, on the other hand, takes 1 day, 7.5 hours - or 31.5 hours - to Breed but sells for 220 Shards.

So for an increase in Breeding Time of x4.2 ...

... you get an increase in Shards of x11

( The Sox won't always result from this Breeding attempt, but that just leaves things on par with the Jeeode / Ghazt time/sale. )

So to answer my niece's question: I had no good reason as to why I was still breeding Jeeode with Rare Jeeode and have switched to breeding Jeeode with Ghazt, or another single element that is on Ethereal Island, and will capture more Shards that way.
