There's a lot of physical and magical heroes suggested, so why don't I present my idea for a sneaky hero?

In the world my character comes from, heroes possess two things: Arete, a skill where they surpass all beings, mortal and immortal, and Hamartia, a mental flaw that cannot be overcome.

My character would be really, and I mean really, good at hiding. When he hides, he can't be discovered (there are loopholes, of course). And his Hamartia is that he lusts for fame and praise as a hero. If there is an opportunity to gain fame, he takes it. It was most likely Kazzok discovering this hamartia that did my character in.

What do you think?
