I'll only give you a few applications, seeing as telling you everything your domains cover is a bit much to do before we even start.

If you're up to fight a bit, you have more options.

Beauty: Authority over aestheticism. Beauty's in the eye of the beholder, a subjective capacity you have the authority to objectively define. It's literally an a priori access to the foundation of reality, the ability to declare what "is".

Knowledge is the raw force of suppliance. The ability to know what is, to perceive "anything" within a given range. Hell, maybe even know the positioning of the other gods. Then compound that with Wisdom, the ability to use that knowledge. Calculation, thought acceleration, memory partition. Ability to use what "is" to calculate what "will be," so on and so forth.

Purity has the highest offensive potential. I'll only say that much, but at its full you have one of the strongest battle capabilities, frankly.

It's a battle of concepts, best of luck~
