Yes, -ish. I don't like Tieflings that are mass-produced according to strict specifications. Being exposed to the magic of the planes (or even just the plane of the Nine Hells, or even just having devil ancestors) should result in a wide range of possible "mutations" / features. Weird eyes, 6th little fingers, black nails, weird teeth, horns, tails, weird ears, weird skin colour, ... or any mix of any subset.

I'm not expecting Larian to add options for 6th finger, nail colour, etc ... but the option to have no horn or no tail is just a matter of including these options in the list of horn styles and ... tail style.[/quote]

No horns is already an option in EA.[/quote]

He’s talking about the no horns option that looks like a normal head, not the “ no horns” option that looks like your skull bone is exposed. Not all Tiefling look like demons/devils. Typically, first generation Tieflings (or ones that were generated by being exposed to the hells) look like the EA ones. Charecters with foul blood ancestry may manifest in many ways. Many can look almost completely humanoid with the exception of a small trait. IE cat eyes, sulfur smell, etc.[/quote]

Look up Brimstone Angels. Long story short around 100 years ago a coven did a ritual with the God of Hell to turn a generation of Tieflings and their descendants into the kind of Infernal Tiefling like you see in BG3. These Tieflings breed true, fuck a goblin and she'll still give birth to a Tiefling. The old school Tieflings still exist, created the old school Planescape way in the setting (Swordcoast Advennturer's Guide), but they are far rarer then Infernal Tieflings.

To thrown another lore twist out there, in addition to Infernal 4e/5e style true breeding horned Tieflings, the revised edition of the PHB coming 2024, has Abyssal Tieflings, and Chthonic Tieflings, no explaination how they fit into the lore or settings.
