A special item called the Thieves Gem in Octopath Traveler 2 can be stolen for the Thieves License reward, which allows players to assign the Thief job as a secondary class to any member of their party. Although each of the eight characters in the game starts out with a primary class that cannot be changed, players are able to earn licenses from across Solistia that correlate to every known occupation. Giving someone a license expands the number of skills and abilities they learn when leveling up, giving players a chance to be prepared for a wider variety of situations.
