Kapsa> na BoardGameGeek mi píšou tohle:
At the start of a mission, each character can equip 1 trinket from the party inventory. But, during the mission, other trinkets may be found. So, each character could end the mission with 2 or more trinkets.

Pockets lets you equip an unused trinket from the party inventory when you play the card during a mission. So, even though you may start with 1 or no trinkets equipped, you could end the mission with several. The only limit is how many spare trinkets the party has in it’s inventory.

That’s how we play it, although I found it a little confusing like you. The important point is the rule that only 1 trinket can be equipped per character at the start of each mission. This means that there’s likely to be spares in the inventory for this ability to make use of. (In later missions)

Ve zkratce, že každou misi musíte začít s jednou tretkou, ale pokud jich máte v družinném inventáři víc, tato vám umožní si vzít další do hry. Tak já nevím... - Maxianimal
