You can only get up to RoS / RoHM. The reson it's like how it is, is because on CF, one normally picks up 4-15 stat potions on a dungeon trip. You can easily get maxed out once you hit level 30 (Well it was easy for me on Gaea[Brigid]) and most people have about 20-50 extra potions of each type. That's why improve stat scrolls and improving rings is so expensive, but for the best you'll have to find them.
