There was an error in the specifications for the Iron Rabbit pets that were rewarded as part of the Mysterious Easter Baskets in which the pets contained buff skills that were not intended.
During a future maintenance, we will be removing the pet buff skills from both 90-day and permanent versions of the Iron Rabbit pet and in both Reboot and non-Reboot worlds.
We sincerely apologize to our players who experienced this error, and for the additional inconvenience caused by the removal of these pet buff skills.
Additionally, the Mysterious Easter Basket sales will end during the maintenance on April 24, 2019. Players who are dissatisfied with this upcoming change and wish to receive a refund for their Iron Rabbit pets may contact Customer Support.
