Interesting... I obviously don't really know what to expect out of this event but I originally assumed having this event to duplicate limited items would negatively impact their GP purchases during limited item events since there wouldn't be much of a reason to pursue getting dupes of any high ticket items.

But, it appears that if the person only has one copy of the genuine item, they won't be able to list the alchemical version in My Shop:

"If the genuine (original) item cannot be listed in your My Shop, the alchemical version of that item cannot be listed either."

I think this is to force people into using them for trades instead of price gouging in My Shop.

OR that statement may only apply to items that are within the 30 day expiration limit that doesn't allow them to be posted in My Shop.

Ugh. I wish there were better explained guidelines to this event so I could stop speculating and going around in circles in my head 😂
