Hello. This is the Gravity Co., Ltd. Ragnarok Online: Zero Operations Team.
Among the contents of the regular maintenance on September 16, 2026 (Wed), a socket enchantment feature was added to the Illusion Underwater Interrupted Helm,
but an anomaly was discovered on the 
Illusion Investigation Team Fin Helm equipment that had completed socket enchantment,
and the department in charge is conducting a thorough investigation.
We sincerely apologize for the inconvenience caused to your gameplay due to this issue, and we will make every effort to ensure normalization is achieved through prompt action.
Regarding related additional notices and normalization updates, we will inform you through further announcements.
Thank you.
