Painter is something of a pariah among other nightmare painters, but his artistic ability captures the admiration of the Torish village where he practices it. 

Runian is a good but not amazing artist, yet the people of his Earth-Lite dimension think he's good enough to control their souls. 

Nomad is short on Roshar, but he's considered tall on Threnody.
