Nobody can be trusted!
Instead of a frail pensioner, you might end up dealing with a fanged rector who’s suffering from a toothache. Convince him to pull out a tooth and—almost—deprive his fangs. And then, you may end up in the clutches of a black dragon, which will shamelessly choose you as its personal healer.
Sorry, I can’t use a healing gift properly. Teach me? And will you admit me as a student to the magical academy? Wonderful! Well then… Where’s my first-aid kit? I’m going to treat someone!
