Since it's a corruption and you lose parts of your humanity through using aether, I was thinking some passives or traits specifically for physical type damage. Just a surface thought, you know what to do best as the author.
Additionally, in most fantasy settings there is aura for the physical type users and mana for magic type. Disregard this if you're not planning on introducing aura, but if you are planning on introducing aura, maybe the nature of the aura can be tainted by aether, nether, or abyssal forming new types of abilities that primarily do the damage type of the corresponding corruption.
