its just a weekly reset

serious? I had no idea... sorry for bothering!
Thank you!

I was quite happy when I found out the log reset with the soldiery cap and 2nd coil each week. It's a good way to get bonus cash and exp for alt classes, a break from endless FATE grinds or dungeon runs :)

Yes, it resets at 4 AM every Tuesday morning. I am wide awake overnight for years, and then do 10 Hests and 5 Dungeons on my new Archer early 20s job so I don't accidentally do 1 or 2 and waste XP on my 50 mage jobs. I can now complete it fully except for Treasure Hunt, since my gathering jobs are exactly tied at 35-36ish each.
