Remind me, why is it illegal to heal outside injuries when you're in the tower? That feels like a really arbitrary thing to have a restriction on, especially given how beneficial it could be to people.
The reason I'm not outright calling it dumb is because there might be some kind of good reason for it (or for whatever umbrella rule it falls under) that I'm just not remembering right now. It's been a while since I last read this, after all.
