if demigods existed and you were a mortal who could see through the mist, technically couldnt you fight anyway? you would just use mortal healing supplies instead of nectar and ambrosia to heal you.

Yes, I think you could. Well, you would't get the gods' help or powers, and it would be more dangerous, but still you would be able to fight, like Sally Jackson (or Sally Blofis?) did in TLO. Actually, Paul did too, though he couldn't see through the Mist.

Yes, we can fight.

Yes, I agree with Roheha, but there aren't that many clear-sighted mortals out there. They're a lot more rare than demigods - at least that's what I've been led to believe.

Yeah i would. Protect the people i care about. who cares if i don't have powers. And i would use mortal healing supplies first. if that didn't work, i would ask a demigod if i could actually use nectar or ambrosia so i wouldn't turn to ashes.

Technically yes, but I'm not sure you'd want to. You don't have cool powers and the gods would probably think you were stupid or something.
