What kind of kids would THESE two have?

[eris404]

The numbers being bandied about are basic genetics (the ratios look like those derived from a Punnet square). Someone pointed out that this situation is one of blending, which I would tend to agree with. The easiest thing to do is assume that there *is* a chance of miscarriage, and a high probability that any surviving child is basically human. After all, the D&D world is chock full o' humans and this might be why... Of course, you could allow the child to take a bloodline (see Unearthed Arcana), or create for it 'feats of the blood' based on Snake Blood (FRCS) and Orc Blood (Dragon 315, Regional Feats of Oerth).

I like the option of human + special "bloodline" feats the best - I'm not crazy about how bloodlines work in Unearthed Arcana, but it's not a terrible option either. Regardless, this situation makes for an interesting background for a (potential) character and should any player (or the DM) to decide to actually play this offspring in the future, using one of these options gives them a great deal of flexibility when determining traits. It's a neat idea and as weird as this might sound, I hope it actually happens.

Maybe something like this?

Statwise maybe human, maybe something totally unique. Sometimes an individual is more than the sum of their parts.

Heh. I didn't think of him until after I went to bed.
Well, we have a precedent, kids: the resulting hybrid offspring is just plain nuts.
