KMS 1.2.187 - Level 250

so its closer to how DFO gets items through nexon portal but its randomized?

I have no idea what you mean. Basically, there's this small part of the website called the coupon box or whatever, and there are certain items that you can claim on the website that'll appear there, most of them have been during preset times, like each of these Happy Time boxes can only be claimed between 2PM to 10PM Korea Standard Time, like those Level 30 Resistance coupons that came with the revamp, or all of the Happy Time boxes, and then you can go into your coupon box and choose to claim the coupon on the character that you have set as active on the MapleStory site.

To clarify, you get all the items listed, but since it just says weapon attack scroll rather than any specific one, I think the scroll you get is random.
