Hello,
This is the Ragnarok Online Zero Operations Team of Gravity Co., Ltd.
We would like to inform you about a change related to the [Event] 
Speed Potion item.
After the regular maintenance on September 11, 2019, it was confirmed that the Speed Potion obtainable from the 
Special Toolbox was being acquired as the [Event] Speed Potion.
This issue has been addressed during today's regular maintenance, and as a temporary measure for restoration, all [Event] Speed Potion items have been collectively deleted.
After checking the data, we plan to distribute the Speed Potion via RODEX in sequential order, so please keep this in mind.
The [Event] Speed Potion obtained through Guild Coins will also be distributed via RODEX.
We sincerely apologize for the inconvenience caused by this issue,
and we will do our best to complete the distribution as quickly as possible.
Thank you.
