I would definitely re-breed to get a froakie with a 31 IV in Spa, it's super important.So, I have a Naive Froakie ingame with a spread of 31/31/31/18-19/31/31. If I'm looking to make a mixed set with the only special move as Ice Beam, does the 18-19 SpA make Ice Beam lose any particularly important KOs?
Can't exactly calc right now so a general idea would be helpful.
