The quest "Picky Sload" is a side quest of the Thieves Guild. It will take a little time to complete it, but as a result, a stolen buyer will appear in the city of Solitude. This quest is worth completing if you collect Barenziah stones.
How to get a quest
The quest “Fastidious Sload” will become available as soon as the hero completes five small assignments from Delvin or Vex in the city of Solitude. At the next conversation-dialogue with Melori, an item about a special quest will appear. To complete it, the hero will be sent to the tan Erikur, who can be found in the Blue Castle. The character will ask to smuggle the captain of the ship - Balmor blue. The hero has to find this drug on his own, and you can do this in different ways.
Passing the quest "Picky Sload"
After talking with Eric, go to the port of Solitude and talk with the captain of the ship "Scarlet Wave" Sabina Nitt. This character is happy to sell you a bottle of Balmor blue. Such a purchase will cost 500 gold. If you try to bring down the price, then, on the contrary, it will increase to 1,500 coins.
You can get a drug without spending money. To do this, get into the lower part of the ship, take a note in the safe. In it you will find information that the potion is hidden in the chest under the ship. The keys to the safe can be stolen from Sabina, but provided that you have the skill "Pickpocketing". Jump into the water on the right side of the stern, open the chest (lock level "Master") and take the drug.
Now your path lies on the ship "Picky Sload." This ship stands northeast of Solitude. You can flush smuggling discreetly. But it’s better to kill all the pirates on the ship, because they have something to profit from. In the cabin of the first mate you will find a chest. Put a drug in it. Here, next to the table, lies one of the stones of Barenziah. On this, the additional quest of the Skyrim Thieves Guild is completed, but there are still many adventures ahead of the hero.
