Trinkets come in 2 colors and you can only equip one of each color.
Blue trinkets give you unique ability.
Red trinkets enhance stats.
Obtaining trinkets
You can get unidentified trinket in ornate chests and completion crates. You have higher chance to get new trinket compared to a trinket you've already discovered.
After you discover trinket, you will be always able to craft the same trinket in the Vault Forge. Crafted trinket will always have 12 uses, while a looted trinket will have 20-30 uses.
You can scrap unwanted trinkets in the Vault Recycler to get more trinket scrap for trinket crafting. More uses left will increase the chance of getting a trinket scrap.
