Collector's Edition Trophy in Hogwarts Legacy

The Collections menu holds everything you have found or earned, and 603 items count: tools, enemies, appearances, Revelio pages, beasts, traits, wand handles, conjurations, ingredients and brooms. Most come with other trophies' work: side quests, challenge rewards, the collection chests in bandit camps, the chests butterflies lead to, and shop purchases. Claim each finished challenge tier's reward in the Challenges menu, because many items are those rewards. Field Guide Pages are the one kind you don't need all of: collect them until every Field Guide Pages challenge is finished.
