If you have already reformed the accessory using the Elvia Accessory Upgrade Cups, you will need to extract the accessory cup before you can accept and complete the quest. If you did not enhance your Cloud Accessory to PEN during the event, your Dreamy Cloud Stones have been exchanged to Dreamy Crystals of Balance and you can still continue to earn these through daily challenge rewards. When you hand over your PEN Accessory, you will be given a TET accessory and an item called Dreamy Crystal of Balance x14. For all players that did not obtain the Cloud Accessory during the event, you can obtain a TRI Capotia Accessory through the Challenge Rewards (Y). This challenge reward can be completed once per account. Make sure all quests are turned on in your Quest Log (O). All of the icons at the bottom should be yellow.

During the Winter Season only (before 22nd Feb), you could obtain a Cloud Accessory from your Challenge (Y) rewards. This cloud accessory had exactly the same stats as Capotia accessories and was automatically exchanged for a Capotia Accessory during the Maintenance on 22nd Feb.
