So my son has decided to play a Tiefling Sorcerer with the Draconic bloodline class feature. Although our Encounters DM shrugged her shoulders when asked and he's already played two sessions with him. Aren't those choices rather antithetical?

I can't find anything that specifically disallows it, but it sounds really edgy to me.

Does anyone know if there is a ruling on this anywhere? I won't spoil his fun if the DM allows it, but I was surprised when she did.


There are no rules that prevent this. Furthermore, there's no in-fiction reason that would prevent a DM from having a world where this is possible.

In most fictional worlds, as in the real one, one person is the product of many bloodlines:

A Tiefling has at least one bloodline that is derived from an infernal. A sorcerer with a draconic bloodline, similarly, has at least one bloodline that is derived from dragons. A given Tiefling sorcerer could easily have both (as well as a bunch of others that are normal and human).

Of course, a given DM's world may make this combination impossible; it might be that, in their particular setting, dragons' blood and infernal blood are antithetical somehow and any such combination is non-viable, or something else with a similar end result of making the combination impossible. DMs are given a lot of explicit latitude in the DMG to create worlds with such details that may impact certain player character–creation choices. But if your DM shrugged and proceeded, then they haven't ruled it out and neither has the game.

    \$\begingroup\$ Once again, SSD beat me to the punch with an answer :p Here's what I was adding: From a quick search, it appears that it is while not common, it is not rare. The reasoning that I found was taken from the 3.5 edition book. Fiends can breed with anything except celestials, and dragons really have no restrictions. Teiflings are descended from fiends, and dragonborn from dragons, so it is not unreasonable to have a draconic heritage somewhere in a tiefling family. \$\endgroup\$ – JohnP Jan 16 '15 at 16:15
  • \$\begingroup\$ @JohnP 3.5 dragonborn are not (generally) descended from dragons, they engage in a special ritual to become dragonborn. I suppose someone with draconic ancestry could also do the ritual and become dragonborn, but that's not typical. \$\endgroup\$ – KRyan Jan 16 '15 at 16:37

    \$\begingroup\$ SSD and John, thank you for your responses. I suppose I should clarify the source of my consternation. Although Dragonborn and Dragon bloodline is not the same thing, they both indeed DO say that there is dragon ancestry for both. The first Dragonborn came from a dragon's egg, and dragon bloodlines come from claiming dragon parentage at some point in the past (yes it also mentions perhaps a pact with a dragon, but you still have to claim ancestry). In the dragonborn entry in the PHB, the reaction to Tiefling is "supernatural fear". That is the basis of my wondering whether this choice is valid \$\endgroup\$ – Escoce Jan 16 '15 at 17:15
  • \$\begingroup\$ It does not guarantee that this reaction is absolute or universal, and not all with dragon blood would necessarily be dragonborn, just as not everyone with an infernal heritage would show the traits of a tiefling. After many generations of breeding with humans, the blood can dilute, for examples. Dragonborn don't look like Half-Dragons, after all. \$\endgroup\$ – Aviose Jan 16 '15 at 18:09
  • \$\begingroup\$ @Escoce The "supernatural fear" line comes from the sidebar on p 33, right? That refers to how everybody sees the uncommon races, not just Dragonborn (you'll notice none of the other uncommon races have this sidebar), so RAW there's no specific friction between Tieflings and Dragonborn. \$\endgroup\$ – GoblinTheodicy Jan 16 '15 at 19:22

Draconic Bloodline

your innate magic comes from draconic magic that was mingled with your blood or that of your ancestors. Most often, sorcerors with this origin trace their descent back to a mighty sorceror of ancient times who made a bargain with a dragon or who might have even claimed a dragon parent

(emphasis mine)

being a sorceror of Draconic bloodline does not necessarily mean that you are in any way descended from dragons. a Tiefling is just as capable of making a bargain with dragons as any other race and as such their descendants are just as capable of becoming Draconic bloodline sorcerors as any other.


Well, given of all of the lore that I have read, dragons can interbreed with almost any species, even an Infernal(Devils) or Celestial(Angel). so if an infernal can mix DNA with a Human and dragon. then I don't see any restrictions.
