Charming Trophy in Ghost of Yōtei

Ten different charms, each upgraded once. Only charms with a Roman numeral after their name can be upgraded. Under Gear > Charms, each one shows the challenge that upgrades it, such as visiting hot springs or a kind of kill. Some upgrade on their own as you collect, and the rest take small combat challenges. Taro, a boy who sometimes turns up at your camp or at tents in Tokachi Range, sells charms that are easy to upgrade.
