It's because you are essentially doing two expensive diamond choices in one. You aren't evolving your familiar to the next level, you are skipping a level to the third level. And when you combine choices like that, that's when the costs get super pricey. We have a couple at 50, I think one at 60, and a very small number of other super high diamond costs. I know one is in ES1 and another in AME1. Off the top of my head, not sure where the others are, but I'm pretty sure there are one to three more.
