Acquiring Quinto
Quinto is one truly talented man. There is nobody around who is as skilled at opening locks as he, so naturally he garnered quite a bit of unwanted attention. To obtain Quinto, you will have to locate him in a mercenary camp where is locked up. Once there, you have several options for how you want to deal with the situation.
Your first option is to just pay his bounty of 200 Crowns. You can haggle the price down to around 170 Crowns if you’re feeling a bit stingy (after all, it wasn’t your fault that he got locked up).
If you’re short on gold, you can instead put your Gwent skills to the test. Play a match against the commander. If you win, Quinto goes free. If you lose, then you’ll need to find another way to free him.
The final option is to just do what you’ve probably already been doing in Hearts of Stone and the rest of The Witcher 3 and just fight it out. You have the option to anger the commander, which leads to a fight. Win and Quinto is home free.
Whichever method you choose, Quinto is now in your debt so just send him to where the stranger awaits and the Open Sesame: The Safecracker quest is complete.
