This is a small mission for those who likes discovering hidden things, and a way to do things.
After completing it you will be awarded with Cyrene Ball Cap (C)
To start the mission you need to come close to red crystal inside Turrelia wave spawn event area, and mess around for a bit.
If you like to slove riddles by your own, don’t open the next page yet 🙂
I wouldn’t have an idea how to make this quest if not a great post by Tempest and explenations made by Gisela Dawes in forum post, so kudos to them.https://www.cyreneforum.com/threads/holiday-2019-cap.8327/
