I am on my first play through as a Setite (VERY hard not to gleefully start over and over again!) and I used lvl 1 Serpentis on the would-be mugger in Chinatown. When he gives you all of his money, Johnny's crone is the audio that plays ("Nobody sees Johnny unless I say so!").
(Thank you for all the indescribably hard work! The new systems are incredible - Haggle feat, Inspection... Nothing feels as broken anymore. I am having to readjust my thinking of, "Well, THAT's mostly worthless...")
