There are two types of trophies in Griftlands. The first type have a form of outfits for your heroine Sal. They are purely cosmetic and do not add anything to your gameplay. And the second - are a set of cards that you can use when starting a new gameplay. It is worth noting that these cards are not included in your deck from the very start. The initial deck remains unchanged. However, you can get new cards when you win duels or you can simply buy them from the shopkeepers.
You get these trophies by collecting points that you earn when you finish a game. You obtain them both for winning and losing. These points are awarded for the number of days lived, duels won, negotiations won, grafts received, the number of good relationships with the characters, final quests, improved cards and earned shills. On the Game over screen you can see how many points you have earned and how many points you need to unlock the next booster. The costumes for your heroine are added additionally every second level. In the new patch there is also a possibility to change your outfit in the "Grog n'Dog" bar when you talk to Fssh.
