But then we all know that the Player's Handbook, p.42 disagrees... as does the Sword Coast Adventurer's guide, p. 118 for the not so small fraction playing in Faerûn or some world derived from it.
Spend too much time with RAW fanatics. And given that even this meme kind of pretends that home brew is the opposite of RAW not acknowledging RAI in any way, I tend to think there are a lot of those. So you always need to know were their RAW is actually contradicted in the rules and which rules don't even work as written and should be considered RAI. It's the best repellent against those people.
DM should re-read the rules since a description of a dragonborn in the rules state they mostly do not have tails, but there are exceptions as well as the fact that "seducing" someone would be a deception or persuasion check as if I said "I lie to the guards" isn't me trying to use a skill called "lying."
