Some help with a hidden quest which very few players discover.
-There are four mysterious letters from Kessler, each are numbered.
-Find the dice-man in lowtown, play him a few times. (Step behind banner each time just as he says) Eventually you will trigger a sleight of hand roll which gives you a clue: you won't be winning without a special set of dice.
-After you have access to Carriwick garrison (or manor, depending who you ask) search the outdoor areas inside the walls. (You won't be able to until very late in the quest) In the southwestern area behind the locked door you will find the Grifter's dice on a stool.
- Play the dice-man with the Grifter's dice. You will win. He will take your dice but in return give you a letter with clues on where to find Kesslers letters, as well the gems pickle-pee the crow is after.
