By the way, one item with a rarity of [★] is a low-value item that can be normally collected around that area. This is not the worst, and there are items below it.
 * For example, weeds that have no medicinal effect are [rare: none] and cannot even be identified. Even for such items, if you process them properly, the rank will go up.
