Good morning from Central Iowa! I had a new curiosity! Brimstone Angels: Lesser Evils seems to say that a tiefling will always have a tiefling child. 5E for FR books more or less are saying that it’s possible for tiefling blood to go dormant. Which one is correct? It's POSSIBLE for tiefling blood to go dormant, but it's not likely.
Moreso than other half-breeds, tiefling heritage visibly predominates in offspring, ALMOST always.
So in the experience of many folk in the Realms, it's "always."#Realmslore
