Got the Second-Rate Medal Collector Trophy in Digimon Cyber Sleuth for collecting 300 of the 500 in-game collectible medals.
Their purpose? Just some achievement trophies and a bit of money 😅 How to get them? Spread over dungeons, drops from enemies or from these kind of gumball machines. Expect a lot of duplicates... Then you bring them to this guy who collects them and underpays you for them. In return you can look at his collection for free 😂
Also got the trophy for raising one of my digimon to level 99 😁
