The truth is coming out!
Shaman magic relies heavily on elemental control rather than mental control. People can be reasoned with. Nature cannot, and sometimes needs some forcing. As such, telepathy, mind-reading, and illusion magic are not in a typical Shaman’s repertoire. The closest they get is a Maga’s ability to converse with the dead or divine a little bit of information off of an object or from patterns (throwing bones, pebbles, bits of wood, etc).
Something tells me that if Uba does learn to read minds and practices on pretty much anyone in this party, she’ll quickly wish she hadn’t.
