By the way, I now have the egg from a chicken and the nugget from a mine. I don't mind a low percentage, and it took me a ton of chickens.
But making the ancillary item (e.g., apple tree in this case) either 1) only available with gems or 2) a rare drop from an adventure with its own difficult ancillaries seems wholly unfair. And that apple tree still only gives a small chance for the golden apple.
