Black Desert Online – Worker Stats Guide
Work speed: The higher this number the faster your workers are able to complete a task.
Movement Speed: The speed you worker is able to reach the location where he performs his work. The travel time is just the distance*2 divided by the movement speed.
Luck: In theory, this stat should increase the chance of getting secondary items from nodes and blue items from production. It has never been confirmed.
Stamina: Each work action requires one stamina regardless of how long it takes. So, for example, a worker with 21 stamina can perform 21 collections before needing to restore his stamina.
Experience: Whenever a worker completes a job he gains experience and with increased levels come extra skills, better stats and the ability to promote to a higher tier.
