About the Everstone trick... I'm breeding an Impish Ditto with a female Modest Ralts. The Ralts has an Everstone, so, following the rules of breeding, there should be a 50% chance of its offspring to be Modest, right?
Well, I've hatched eleven eggs, and 4-5 of them were Timid. I'm assuming it's just bad luck, but I just wanted to make sure. Also, I read somewhere in the forums that natures are passed down through Ditto since it apparently takes the role of the female, so I'd have to get a Modest Ditto. I'm not sure if I necessarily believe that since, technically, that would mean breeding with a Ditto would always produce a Ditto.
edit: Hatched four more eggs, and two of them were Timid. :/ The probability is too low for it to be a coincidence, I think. Does this mean if I try to use the mother Ralts to get Modest Pokemon, I'll most likely run into Timid ones instead?
