Relic Awakening can be found in the lower right corner of the game screen in [Relic] > [Awakening].
When the relic is awakened, the default options for relics are greatly increased,
as the relic's rating is increased as well, activating the property skill that matches the rating.
Additionally, every time a Relic is awakened, you can acquire Magic Circle points that can activate the Relic Magic Circle,
and the number of points you earn varies according to the rating of the Relic.
