Stranger Things 3: The Game

In Hawkins Square, near the Pan-O-Rama, is Fanatic, who insists that you will need trinkets to protect yourself. Speaking to him will spawn a sidequest, where you will need to buy a trinket from him for $5 – and for the next three chapters, he'll have another trinket-reward sidequest for you. You can also find/buy crafting items and make the trinkets yourself – sometimes you can even find trinkets. However you go about it, having five in your inventory will unlock this trophy.
