A tiefling and a half celestial have a baby....

[2bz2p]

I'm not sure there is anything RAW about this, but in our game there is a marriage between a Half Celestial (Azata) and a Tiefling. Both are good, raised in the same faith, both clerics, the Tiefling is 1/8th fiend blooded, even has Pass For Human feat, and more and more backstory I'm not gonna go on about.

The couple are expecting their first child. The common assumption is the child should be an Aasimar under P1 rules, as Aasimars are "humans with a significant amount of celestial or other good outsider blood in their ancestry" and the Tiefling is mostly human. Does that seem right to you all?

[Diego Rossi]

I would agree with you, but it is mostly a problem of narrative, not a problem of rules.
So the best option is "what works best in your game."
If I was either of the parents I would ask the blessing of my good, and see if we could deliver the baby in a consecrated area to edge the chances of the best outcome.

Kudos to your group, as the game seem well fleshed!

Aasimar and Tiefling don't necessarily pass their celestial/infernal traits on to their children. A Tiefling and a Human would probably have a Human child, but maybe their great granddaughter would show infernal heritage.

A Half Celestial probably would though (I'm less familiar with this).

So yeah my understanding is that you'd probably end up with an Aasimar or something. Maybe even just a Human, but more likely Aasimar than Tiefling.

Although if you're the GM remember this is all chance-based (it's a bit like a recessive gene) so you could just have the child be a Tiefling to mess with them if it suits the story.

tieflings and aaimars generally come from parents who are neither. they don't really pass their genes on for sure as they tend to be very diluted.

the half-celestial however is far more likely to pass its genes on, if it was me i would do a d100 1-98 is celestial 99/100 is tiefling. you could remove this by doing things like that diego above me said.

[Lathiira]

I've said it before, and I'll say it again: never mix genetics and role-playing games. That way madness lies ;)

[AwesomenessDog]

Even if they do pop out a Nephilim-type halfbreed, unless you as the GM are willing to let them create an even more powerful, munchkinny, super custom combo of the list of choices already available Aasimar and Tieflings, the simple solution is to say "yes, you are a half-celestial/half-fiend, but just as being an Aasimar-elf or a Tiefling-halfling doesn't change the stats of the Aasimar/Tiefling, you will have to pick either Aasimar or Tiefling and only get the stats as one of them."

[Zepheri]

Since the half celestial have a strong gene I will say that the baby have the celestial traits (8-9/10 genes); an only have some minor aspects of the tiefling since he is a more diluted race (1-2/10 genes) so the baby could have some horns, pointed tail, etc.

Example: assimar with horns and bat wings.

[Rennaivx]

Peri-blooded aasimar would be my choice, as their description already talks about having warring influences from multiple bloodlines. It involves a little bit of reflavoring, but definitely worked for the character I made that had both fiendish and angelic ancestry.

Heredity of aasimar and tieflings is unpredicatable.

I would say there are roughly equal chances of aasimar and human, with a smaller chance of tiefling - say 45%/45%/10%. That assumes both a tiefling that is mostly human, and that the other half of the half-celestial is also human. If they were both (say) halflings, then obviously halfling would replace human in the above.

If the other parts are things that would normally be incompatible (say dwarf and elf), then that brings the supernatural side to the fore - in that case I would ballpark the probabilities at 70%/30% aasimar and tiefling.

However the first generation ends up, there would still be a small chance each time of aasimars and tielfings popping up in future generations, even in lines that have been fully human up to that point.

Thanks all. As the Half Celestial/Half Human has a dominant trait to create an Assimar child, and the 7/8 Human 1/8 Fiend Tiefling has a weakened trait for Tiefling, I'm going to have the player toss two d8. If either shows 4-8, it's Assimar. If both show 1's, tiefling. both 3 or under, but not double 1's, Human.

This keeps it fun, 'cause chucking dice is fun, and I don't need the child to be a particular result for story!

AGAIN -- Thanks for the feedback.

What if they have twins?

1 can be assimar and the other tiefling

[AwesomenessDog]

You just roll 4d8 then and yes, it has a 2.34% chance to happen.

Peri blooded aasimar imo

[Falkyron]

I had a character who was a full-blooded devil PC have a child with an aasimar PC. We went with RAW and the child was a half-fiend aasimar, humorously.

Any thoughts on tbat?

Why peri-blooded?

The celestial parent is an azata, so if it is going to be a specific aasimar type surely it should be musetouched?

Because Peris are what happens when celestial beings have fallen angel ancestors so it makes sense for the blending of tiefling and half celestial to create them.
