I think a Stat IV Modifier would be a great addition to the game, as you know, you can already purchase a MAX IV Modifier from the Pixelmon Store for $50.00 USD, some people may wanna modify a single IV Stat rather than all of them, this way they can save money. I think the price of this should go for $8.33 as there are 6 category's, Spd, Atk ,etc. Meaning 50/6 = 8.33. This can help a lot for breeding, etc. I can also see this idea boosting the sales of the Pixelmon store!
