There abruptly appears a beautiful woman in beautiful clothes who looks extremely annoyed.
She looks around at her surroundings, and sighs.
He sends it.
It hurts as described--not only the magnitude of pain of a broken bone, it actually feels like it, or like a very intense jar.
Along with the pain comes information--this is what Sympathy feels like this is what Effort feels like this is what Conquest feels like--and, this is how you manage the mental side effects. Self-examination and modification. Exactly the sort of thing she's good at already.
"Ow. ...Hm. How do you suppose the pain effects would respond to deadened nerves?"
"Well, I'd rather not kill them permanently, but I can do a lot of things."
"The pain doesn't necessarily have to be experienced, but it does have to exist; disconnected serves better."
"I would naively expect Conquest to be harder than the other two to use at first, since it's instant, is that right?"
Good. "As I suspected I do not have much affinity for Conquest but I can do Sympathy and Effort just fine. And now I should probably stop for the time being; I'm not going to be a magical asset in the coming excitement."
"True enough," he admits. "I might suggest finding someone to tutor you in basic magical self-defense measures, though."
"Especially if Mandos isn't getting backups from here, that does not seem unreasonable."
