When you select and unlock a Cell, you gain the stat assigned to that Cell.
Once you max out and unlock all Cells on the page, you can proceed with Awakening.

When Awakening is performed, the star grade of the selected cell and the cells within one adjacent space will change according to a set probability.

※ Awakening pages are unlocked based on character level and the number of cells completed on previous pages.
※ Materials required for unlocking and Awakening can be obtained through equipment dismantling, quest rewards, manuals, rifts, and treasure chests.
