How about using elementals as ears and eyes? Like blind Heir of Void having a bunch of shadow-monsters with many eyes that are always looking and around which the Heir seems to always know what is going on around. Seer of Hope having angel scouts with whom they share telepathic link. And many other.

Don’t see why not! And yet I cannot help but imagine like, a Blind Hope Player with an Angel tied to a leash like a Guide Dog.
