I dunno the exact method of maxing it because I don't really see a clear enough guide. I rarely used Professions before so I wouldn't really know. I heard the "Arrow Method" before but I'm not sure about it.
How many crafts does it take and how much would it cost in total to get to 100 on diligence?
Bonus question: Does diligence effect work on Clean Slates from events, 20% event scrolls or 40% event scrolls? I dunno what are considered "Special Scrolls" but does anybody have a list too?
Thanks in advance :)
