Hello.
This is the Gravity Ragnarok Online: Zero Operations Team.
We would like to inform you of issues that occurred after the regular maintenance on December 19, 2018. Please refer to the information below.
- Regarding the Third Gift Event of the 1st Anniversary Celebration Party
Regarding the "1st Anniversary Celebration Party" event's third gift, which was intended to be a weekly quest — "Hunt every week and receive a buff + EXP gift!!" —
We have confirmed that after the regular maintenance on December 19, 2018, it was incorrectly applied as a daily quest.
As an apology for this, the event will be run as a daily quest during the period below.
Period: After the December 19, 2018 regular maintenance ~ Before the January 2, 2019 regular maintenance
Details: Changed so that it can be completed as a daily quest
(Once the event period ends, it will revert to the original weekly quest.)
- Regarding the Winter Limited Costume "
Costume Santa Hairband (item)"
We have confirmed that among the winter limited costumes newly added on December 19, 2018, the item "Costume Santa Hairband (item)" had some hidden options applied to it.
The applied options are as follows.
A certain chance to transform into Antonio for 5 seconds upon physical/magical attack,
During the transformation duration, Flee increases by 10
Since costumes obtained through 
Gel Star (item) exchange in Ragnarok Online: Zero are not supposed to provide options,
this option is scheduled to be removed during the December 26 regular maintenance.
However, the transformation option that has already been applied will remain as is, and additional explanation will be added to the item description.
We apologize for any inconvenience this may have caused,
and we will strive to prevent similar issues from occurring in the future.
Thank you.
