Further to my Rotom building, I thought a good idea might be to put hidden powers on them as they have a fairly limited movepool and the hidden power might coincidentally line up with covering one of their weakness (So I have 5 Rotoms and whatever one had a Grass type hidden power would become Heat Rotom or whatever) however the big flaw in this seems to be becoming apparent. All my Rotoms have 5 IVs and 31 with their Attack being the random stat. Well so far every single time I figure out their stats, all the online calculators say the uneven Attack IVs I'm getting result in a Dark type Hidden Power and the even Attack IVs result in a Dragon type hidden power, so am I just really unlucky, or once you get 5 IVs at 31, does the remaining stat only give you one of two types based one what stat it is? So no matter what that Attack is, from 0 - 31, will it ALWAYS result in a Dark or Dragon type, or am I just insanely unlucky? Thanks!
