How do you become a demigod?

I wish I knew.

You don't become a demigod. You're only a demigod if one of your parents is a god and the other is a human.

yes, the Word demigod means Half god, another name is Half-blood.

Answer 2:

You are a demigod if...

a) You have read Percy Jackson and

b) Your best friends has cloven hoofs hidden in his sneakers.

In all other cases you are not.

Have a God for a parent.

Its literally impossible to be one but do pretend.
