Larceny

Overview
Larceny is non-production skill. It is leveled by the opening of coinpurses that are dropped from most mobs. Opening coinpurses costs a number of labor points dependant on the level and rarity of the coinpurse. Opening coinpurses does not give you infamy points.

The only benefit of leveling your proficiency is to decrease labor cost and increase speed of opening coinpurses -- "We checked on this recently as rumors have spun up about Larceny's benefits. Leveling up Larceny only decreases the cast time and labor costs of opening pouches. It does not impact drop quality nor crime-related activities, despite the name."
