Sorry to be a bother again, but I have another rules question:
I want to duplicate the Blindsight ability in DnD, in order to simulate the whole supernatural awareness martial artists have in Shonen anime and manga. It's going to be one of his powers. The thing is, I'm not sure how to do it. Supersense seems like a likely candidate, but it doesn't feel like it'd be something like sonar and I'm not sure what "magical detection forms" could be used for.
