Notes
Spoiler Alert! We have some more information about how to perform this quest but recognize you might want to try it on your own before we tell you the secret...
Speak to Antaikolon to be teleported to the Star Spring. He will then summon a Hexagram. There are 3 pads around it. You need to push the one that is sparkling (try 3rd person looking down on the device). You need to click again JUST as the last casting ends. Keep doing this until you get it right and it completes.
