v.93, Big Bang Update Notes

Because in KMS you only get ONE SP reset scroll per character. The SP reset scrolls will be given until July 21.
There is no second chance if you screwed up distributing your skill points.
Though, actually there is a second chance but you can only get it on one day.
An event ‘Hot Time’ will be held on the 10th of July.

To get another SP reset you must be logged on from 2:30 PM till 2:31 Korean time. This event comes with a bonus, you can win other prizes such as Timeless items and Cash Shop items.
Anyway I didn’t screw up my SP so there is no need for me to play during 2:30 PM.
After this event there will be no SP reset scrolls given to you.

There is no need to panic over a single minute of an item you'll get for free at launch.
