Unlike Prism, it does not achieve harmony with light and dark, but rather overcharges the element being used. If we proceed in this way, we can use three types of Light Energy to fill the "Transcendence energy." For example, if we want the Void Subclass to use "Transcendence", we must use Arc, Solar, and Void types of damage to fill the energy, and none of the three are missing. If one type of damage is missing, "Transcendence" cannot be used. Or it can be achieve harmony with the opposite element. For example, using Strand type damage to fill the "Transcendence Energy" of the Void Subclass. Anyway, it's just an idea.
