Thank you very much. So, there is no change in the stats just in the description.
I got it now,.
And a last question... when the event is over, will the stats for exp and drop rate be removed? Or are they permanent
Since this is a one time thing, and the items will never be released again, I would assume that the stats will not change.
Banrukai is correct. I verified this with Leo when the event started. He said the stats are permanent.
