Question

shamans.
priests.
oracles.
witches.

Explanation:

Shamans are part - time religious practitioners. They are believed to have the power to travel or contact supernatural forces directly on behalf of individuals or groups. Priests are usually full - time religious officials in organized religions. Oracles are more about giving prophecies. Witches are often associated with using magic in a more general (and sometimes negative - connotation in some contexts) way rather than the specific role of direct contact with supernatural forces on behalf of others as described.

Answer:

shamans.
