No worries!  I'm a little out of practice, it could be I was super unclear!<br/><br/>Deris Feruk is the son of the guy who has the necromantic tome.  He clearly is uncomfortable around magic (and we know from some narration that he is a witch-hunter) and Yula noticed that!  The runner is casting a spell of some kind and Deris is looking freaked out by that.  One thing that is potentially useful is the knowledge that Deris would be rather uncomfortable with his father claiming a necromantic tome, something that you likely can use AFTER the fight!<br/><br/>Did that clarify?
