serebii.net says you get them from a random event.
Such as Oichi and the jigglypuff charm.
but someone on one of the boards said you can't get the jigglypuff charm if jigglypuff evolved into wigglytuff already...
I have yet to get any of these items sooo plz help a guy out
I had wigglytuff when I obtained the jigglypuff charm... I haven't gotten the unifier crystal but I do have the other 2, I had valora and dragnor maxed out and had level 2 nobunaga and tadakatsu, Ieyasu and Ina. obtained nobunaga's a month after he was level 2(he was training in dragnor) and the same for Tadakatsu.
