@Basementdweller09 the problem is that, "just the skin", the blessing made her hair, eyes and skin black... ok
now with the other blessing her skin changes... but not the hair, not the eyes....
OK
why she did not got grey/white hair?
why her eyes are still black?
White hair on black skin would be much more "shocking" if that was the intention, changing just the skin color was on purpose, don't be innocent, i just explained why it was malicious.
Her parents dont have black hair, her parents don't have black eyes... no one have, that is as much influence of the dark spirit king as her skin, be Claudia be like:
