As I said in the other thread, we should avoid using % when a modifier may apply. % are mainly for random treasures or random encounters (which I don't use heavily, I prefer to choose as a DM), random chance of getting wings if half-celestial or half-fiend (which, again, I don't really like, since that should rather be decided by the DM -- and the player if it's a PC), for fiends summoning some of their ilk (which, in my opinion, is a bad idea and a leftover from 2e, but there was another thread about that), and for stabilization roll (idem).
So, let say we rename this second table to something like "Successfull pregnancy modifiers". At the base, that would be a Fortitude saving throw, at let say DC 15. Then we add these modifiers to the DC:
Baby Race:
Dwarf: +1
Elf: +4
Gnome: +1
Half-Elf: +2
Half-Orc: -1
Halfling: +2
Human: +0
----------------
Orc: -2
Goblin: -2
Hobgoblin: -4
Per extra baby: +2*
* Twins: +2, triplets +4, etc. If the save is failed just because of this extra baby modifier, this means that part of the babies survive, and part are miscarried.
So, a woman waiting half-elves twins would get a Fortitude save DC 15+2+2 = 19. If she roll a total of 19 or more, congratulation to her. If she roll a total of 17 or 18, she'll only birth one child. If she roll a total of 16 or below, the two babies are stillborn.
Let's take now a orc woman pregnant of a triplets of half-orcs. Her DC will be 15-1+4=18. A result of 18 or more means 3 babies, 16 or 17 means 2, 14 or 15 means only one, 13 or less means none.
My numbers have been estimated quite simply, you have a scale of DC. Medium breeders (humans) are at 0. Slow breeders are at +2. Fast breeders are -2. If frail (racial Con penalty), you go up one degree of difficulty higher, (i.e., elves go from +2 to +4). If stout (racial Con bonus), you go down one degree (dwarf, gnome, hobgoblin are example of that). Cross-breeds use the DC adjustment closest to their parental average, rounded up if need be.
+4
+2
+1
0
-1
-2
-4
Also, with this table, it is easier for an elven woman to birth a half-elf child than a full elven one.
This certainly may benefit from some fine-tuning.
