Yes, I know the requirements on how to get said skill, each ego has a different attack but...does the ego gender have a different incarnation?

I'm asking this question because I've only seen one gender of all incarnations, and they're all female (save for the mace, I saw the male one, not female.)

My question would be answered if someone were to present male incarnation videos though. (And a female one for the mace.)

Yup. I've heard that the male spirit sword hits 1 enemy with a really strong attack, and the female spirit hits multiple enemies with an attack that's weaker then the male spirit's attack. I don't know about the other spirits and I don't have any videos either sorry.
