There are many things you can do to prepare for the Chronicles of a New Era – The Crystal Tower’s new rewards. The first thing you should do is to upgrade your weapons and armor. Those two things will make it easier to complete quests. Next, unlock the quests associated with the Crystal Tower. The Labyrinth of the Ancients and the Crystal Tower will lead you to the quests.
The first quest in the Crystal Tower series, Legacy of Allag, can be found near Mor Dhona Aetheryte’s Toll. If you want to progress in the main storyline, you will need to complete this quest chain. Once you complete this quest, you’ll be able to access the next Crystal Tower quest, Light of Hope, which is required for the Main Scenario quest.
