This one's a little tricky, if we want both reasonable safety and accuracy, so please pay close attention to the spirit of the question.

I could list a whole slew of examples, but it occurred to me that odds are this would be an exercise in futility. Instead, please answer yes if one or more of the following definitely applies:

A) It is blisteringly obvious that your role power matches your character.

Examples
You are bulletproof, and your character has nicknames like "Man of Steel" or regularly gets shot with bazookas and machine guns and death rays with little meaningful effect.
You are a mason to some other guys you're teamed up with, like you and X are part of the "League of Badass Hero Dudes" and can talk at night.
You're a miller, and regularly are described as a bit of a lone gun or black sheep or semi-reformed criminal who follows nobody's rules but his own, and everyone always mistrusts you.
You're a Doc, and you have "Dr." as part of your name.

B) You are vanilla

C) The mod clearly connected the dots in your flavor fluff. "Superman, with your X-Ray vision you can see through walls and investigate one person a night..." or "Batman, you have acquired the SPLOG, which allows you to..." or "Because of your extreme paranoia, and excessive caffeine addiction, you can stay up all night pointing a gun at the door to your room."

In other words, if its not really obvious from what the mod said or from your characters description, say no. Mat, Thom, and Lan probably do know way more about treating wounds than Average Joe, but would make bizarre docs with Nyneave around, and should say "No" unless the mod specifically said something like "You have found a ter'angreal that heals people".

Please don't reach for a "Yes", if it's not clear, say "No".
