Spy's Luck is skill in the Sabotage skill.
This ability allows a second chance at lockpicking, electronics, and hacking attempts. If you fail while this skill is active, the pick/hack resets and you can make a second attempt - though failing a second time will have the usual consequences.
Cooldown: 300 seconds
Breaking a lock with this skill active will also trigger Spy's Luck.
(Which is great if you're at a door with a very difficult lock - if you can't make the timer, just kick the door in.)
