Do you need to level up Microchu with only potent items as well to get to level 24 before you infuse it? There was a topic that says that, but it doesn't make sense to me why you would want to do that.
Every time you read this, squirrels randomly burst into flames. Think of the squirrels.
I don't see why the stats would matter tbh... You're infusing the ABILITIES, not stats. It could just be a cost thing though. You can easily farm all the potent materials for free, especially up to the point of leveling the silver choco, whereas buying the mats from Chocolina could be problematic, expensive, and possibly money better spent on other things.
