Thronebreaker: The Witcher Tales

Trinkets are a certain type of card that give you bonuses to your card's health or cause damage to the enemy cards, among various other bonuses. These are collected as you progress through the game; in each chapter there will be at least one card that you can build by finding three pieces of it in different areas on the map. You will also be given some of these from side missions and puzzle, so acquiring ten throughout the game will be almost guaranteed.

Here is a list of more than ten trinkets for you to reference should you need it:

1. Decoy: Acquired from the puzzle 'On the Range' in chapter 1
2. Elf and Onion Soup: Acquired from the puzzle 'Some Trolls Have All The Luck' in chapter 1
3. Mardroeme Bear: Acquired at the end of the Lippy Gudmund battle in chapter 1
4. Dimeritium Bomb: Found in 3 parts throughout Lyria in chapter 1
5. Lyrian Horn: Found in 3 parts throughout Lyria in chapter 1
6. Lyrian Merlot: Acquired after completing 'For Better or Worse' in chapter 1
7. Morana Runestone: Acquired from the puzzle 'Hard as a Rock' puzzle in chapter 1
8. Fake Floren: Given to you for completing the 'Battle of Dravograd' in chapter 1
9. Royal Decree: Given to you by King Demavend III at the end of chapter 2
10. Dazhbog Runestone: Acquired from the puzzle 'Born of Fire' in chapter 2
11. Reinforcements: Given to you after defeating Caldwell during 'The Siege of Tuzla' in chapter 4

As with many of these achievements, you will unlock it naturally as long as you are completing everything on each map. There are more than thirty Trinket cards to acquire in the game, so finding ten will not be a great task.
