I was told to not correct misconceptions in the question comments, what should I do instead?

Question

Sometimes, the asker includes misconceptions in their question. The most recent example is here, where OP assumes the Barbarian resistances from rage only work for non-magical effects.

In these questions, we usually get a comment in the question saying "Hey bro, that's not how that rule works" from someone trying to help the asker. Usually these people are told that it should not be done in comments.

So, what should the person trying to help do?

I couldn't find more examples because we can't search for comments. But this happens quite frequently from what I see.

Related: How do we handle it when the asker's problem is just that they're confused? - but there, the misconception is the problem. In this case, it might be a minor detail, like in the middle of a question saying that "flanking is RAW" when it's an optional rule.

Answer 1

Correct the misconception(s) in the answers

Unless the misconception makes the question unclear about what the asker is actually asking, usually these questions can be answered. If the misconception is clear, but a fundamental/core problem in the question, an answer substantially dedicated to clarifying that misconception should be fine - then proceed to answer the actual question after having clarified that concept.

If the misconception is minor and you don't think an answer only for that would be enough, answer the question normally and add that as a detail/side note. If you don’t have time, energy or can't provide a full answer to write an answer, wait for someone else to do it. If the someone else doesn't touch the misconception, check the next paragraph.

Finally, if the misconception is minor and there are already other answers that answer the core problem (as in the example question) and you don't want to replicate an answer just to include that detail, I would suggest to add that as a comment to an answer, suggesting them to add that detail.
