Rosie's thing about healing magic is no surprise - actually, thinking on it, Mithrun thinks that might have come up around the whole... fiasco back in Amani. Something to do with that planned meetup that never happened.

That prior knowledge is easier than some to set aside for the sake of a normal conversation with someone he's pretending only to have recently met.

He just nods, and answers: "Some use illusion magic when healing for a similar effect. If you know what you're doing, it isn't terribly difficult to tamper with a subject's senses to change how the pain is interpreted. Not everyone does it, though; some consider the risk of side effects too great, or the extra mana usage wasteful."
