Should there be a list of opposite powers?
I guess so, but it's kinda hard to find every power with an opposite equivalent :/
But Duality Embodiment has some examples, such as 10th Dimensional Physiology to 0th Dimensional Physiology.
I think it should be a actual thing,too.
Not every power have a distinctly written opposite in every aspect.
But many still do, especially the elemental ones for a starter.
What do you think?
