I read somewhere that breeding Ditto with Volbeat has a 50% chance of getting an Illumise egg, and vice versa. Is that true?
Shockingly and against any logic; this is true. You may breed Illumise with Ditto for Volbeat - and it should work the same way for Volbeat. I also heard, that Nido-family is capable of this too, yet I haven´t checked this
