How do you handle interspecies crossbreeding in your games?
I don't, and see no reason to do.
>>96573691I cut out every single 'Y' for Dragons - Dragons only breed with dragons. And even if they can technically breed with Kobolds, to lower themselves to do so is unthinkable.Dryads, Satyrs, Nymphs, Merfolk and Sprites can all breed with each other but not with anything else.Fiends and Celestials don't breed at all, they're ascended/damned mortal souls and incapable of procreation.Humans are allowed to Breed with Dwarfs and Gnomes and Halflings, who are also all allowed to breed with each other.
>>96573691In every homebrew setting I write all sentient species can interbreed. The offspring will always be full blooded member of the race of their parent of the same sex. There is a potential there to kill of all members of one sex in a race, reducing them to single sex species, though I've never had that happen.
It doesn't happen unless they're human or elven, in which case they can impregnate anything or get impregnated by anything if they try hard enough.
>>96573691You first. Be detailed and specific.
>>96573691When two characters really love each other, if they hold hands without any gloves on a baby is born from a nearby flower. Then a 1d2 roll determines the inherited race.
>>96573691Interbreeding happens when an alien bug thing implants DNA it had previously stolen to other species females.Can happen between sapient races, or animals, or even plants.The host parent rarely survives the childbirth, but the interbred child has traits of both parents species.
>>96573691There is no such thing. Different races can fuck each other but due to the different biologies it never results in a viable pregnancy.
>>96574245elfs are psychopaths from a parasite dimensionnobody wants to know what creates the changelings they leave with families
>>96573695Thread should have ended here
>>96573691The only inter species hybrid that exists in the world is an attempt to recreate God.
>>96573691with a fireball
>>96573691Oh boy This thread again.
>>96573691Only Humans (and Dragons) can breed with other races hints the "half-x." (That's their specialty.) You can do the actions but it be like the fags butt fucking each other. Nothing is going to come from that other then most likely catching a STD.
>>96573691Enthusiastically.
>>96574310See the OP pic for reference.
>>96573691Giving Humans a "Maybe" with Centaurs is so fucking horny. You know exactly what they're saying with that pairing, just like Giant having all those "Maybes."
>>96573691Like this.There's fierce competition between humans and dragons at the higher strata of powerful beings to see who outfucks the other.>>96580745I like this guy.
>>96573695/threadAnd yet bumpfag will carry this thread till at least Halloween
>>96573691Almost nonexistent because I find the idea offensive. Misceganization is gross enough without us crossing species.I guess if it's non-racemixing but species-mixing it's acceptable. Elves are Aryan, right?
>>96573691>no species can not reproduce with itselfLame
>>96573691 like this
>>96573691Setting is post-apoc techno-feudal science-fantasy. System is GURPS.PC races are:>Androids: fully synthetic humanoids. The lowest class. They form the basic labor force of most City States.>Bioroids: vat-grown cyborgs with organic bodies and machine brains running AI programs. The second-lowest class. They serve in low-class jobs that necessitate a softer touch.>Chimeras: gene-modded humanoids, or the descendants thereof, who have spliced human with animal DNA or genemolds based on mythical creatures. These make up the middle class in most City States. They often possess superhuman strength, speed, and endurance, and sometimes also exhibit psionic talents.>Mutants: humanoids who have been fully transformed by the corruptive energies of the Zones. They often possess exotic powers and physiologies that defy scientific explanation. Most are hostile to human civilization, although some Noble Houses keep a few exceptional Mutants under tight cybernetic shackles as formidable God Warriors.>True Kin: true humans who possess the genetic authority to operate Old World high technology. Organized into Noble Houses with their own technologies/authorities, they form the ruling class of most City States.>Voices: disembodied consciousnesses who are birthed from the strange energies of the Zones and inhabit energy fields and data networks. Most are seen as Daemons, although some settlements and Noble Houses may regard a friendly Voice as a Guardian Spirit.Interbreeding chart is as follows:>The child of a Mutant and any other species is always a Mutant.>The child of a Chimera and a true kin is always a Chimera, except when breeding with a Mutant, which always produces a Mutant.>If designed to conceive, the child of an Android or a Bioroid and a True Kin may produce a Fell Kin: an infertile bastard child of a Noble House who may operate their technology, but never reproduce.
>>96581587One more thing:>Mutants and True Kin lose their special abilities/genes if directly cloned, artificially inseminated, or grown in an external womb; only live natural birth can reproduce their full capabilities.
>>96581595that makes no sense
>>96581595what is the difference between an android with a cloning tank in it and an external womb/cloning bank/artificial inseminationi smell a eugenics rape guro - magical realm
>>96573691Every species has a Fertility Die, size determined by how fast they breed. Every time they hqve sex with a potentially viable reproductive partner, GM rolls the die from each partner. Matching dice mean impregnation. Si goblins, kobolds, ratlings and other fast breeding types use a d4; orcs, halflings and others that breed a bit faster than humans but not much use a d6; humans and species with similar reproductive speeds roll d8; dwarves, gnomes, lizardfolk and other slow breeders have a d10 and finally elves or whatever "dying because of low birth rates" species are a d12. Dragons are always assumed to match their partners die and beings from the realms above, below or sideways from reality have total control of their fertility/virility though a partner of overwhelming power could force the issue. Hybrid children are treated as the same species as their mother but swap around 1/3 of their racial traits with ones from the father. Multiple generations of different hybrid mixes can get pretty mixed up.
>>96581252Lmao you crazy bastard. Where do humans come from then?
>>96573691Depends.In one, they don't. Because there is only one species. Humans, elves, dwarves, satyrs, mermaids, giants ... all the same species.In the other, they don't. Because they are different species.As you can see, I have a wide and nuanced variety of options.
>>96581252nahnot enough interbreedingwe need a left to right downward sloping diagonal line of N
>>96573691How do you? Provide a detailed and insightful answer that's not obviously AI-generated.
>>96573691In my setting the races were all made from the same basic template by the gods, so they can all have kids together, but the child is almost always the race of the mother, with some minor features from the father’s race.
>>96582826>android with a cloning tankI made a mistake. Only Bioroids are supposed to produce Fell Kin. Androids merely produce infertile clones without any genetic authority.>eugenics rape guro - magical realmThe Noble Houses carefully cultivate their bloodlines to maintain their genetic authorization privileges. Marriages between houses exist to bring in new blood (and access to new technology) while sowing alliances. But otherwise, the blood must not be diluted too thin, lest outsiders gain access to their technology, or they lose their authority altogether. It is not unusual for the young men of the Noble Houses to sire Fell Kin with their personal bioroid maids when a need arises to produce servants who can operate their technology, but who are invalid to inherit and unable to leak their bloodline authority.Meanwhile, just as the Noble Houses practice eugenics themselves, so too do they among their God Warriors. The Houses run breeding programs between Mutants in an attempt to reinforce their most potent exotic powers, at the risk of greater mental instability and exposing long-term health problems in recessive genes. Breeding between Mutants and Chimeras often has extremely unpredictable and dramatic results. On the flip side, hybrids between Mutants and Bioroids are easier to rear and care for in great numbers, but have diluted abilities and are almost always sterile after one generation. Breeding with Androids is impossible, and breeding with Humans is strictly prohibited (breaking such a taboo is punishable by decimation of the offending Noble House, a punishment which is carried out by the other Houses). In many cases, non-Mutant mothers do not survive childbirth.>>96582813To produce proper God Warriors and valid Noble heirs, they need to fuck. It's my magical realm, and I get to make the rules.
>>96574245>I cut out every single 'Y' for Dragons - Dragons only breed with dragons. And even if they can technically breed with Kobolds, to lower themselves to do so is unthinkable.The chart is unconcerned with what dragons will actually do, only what they can do.By your own description, they have at least one Y on the chart.
>>96573691Get the racial traits of both parents, since half of all racial traits are downsides. If some racial traits are the same (either disadvantages or advantages), knock off some of the other variety to balance things out. If interbreeding with humans, who have no racial traits and represent the baseline, knock off half of the other parents racial traits.Could be persuaded to do something else on a case-by-case basis, since the racial drawbacks relieve ability slots that racial features take up. Every playable race is technically just a human to a really fucked up human anyways, so some cross-compatibility makes sense. Someone genuinely trying to fuck a monster, spirit, or some other weird shit has got another thing coming if they expect that to produce anything.
>>96583293Damn you crazy bastard. I don't even have interbreeding in my setting but when you put it like that maybe I'll have to add it... was what I was going to say until I worked out the mathematics on this. Turns out its entirely equivalent to take the largest of the two dice and impregnation occurs if you roll a critical success on it (take your pick of rolling a one or max).
>>96573691Interspecies breeding is impossible and in some cases body fluids are toxic.
>>96573691Humans, elves and orcs are Apex Species and thus produce half and half children together. Otherwise all children match the species of the mother, with a few exceptions. >Dragons always produce half-dragons regardless of parentage of partner >Gods always produce Gods, regardless of parentage. They start as a godling, matching the parentage of the partner, before becoming a full God later. >Tricksters like sprites and changelings always produce like >Despite their reputation, goblins are sterile. No one knows where more goblins come from.
>>96573691>How do you handle interspecies crossbreeding in your games?Races can crossbreed within their immediate taxonomic groups, but not outside. Mother determines/preserves phenotype. Humans & Centaurs can breed. Genetic flow and intermarriage is so common back and forth in some of their populations that they do not culturally recognize crossbreeds. Ogres can breed with any Ogroid (except Cyclopes): Orcs, Oni, and Ettin, but none of the other Ogroids can do this. In other words there are only half-ogres. Dwarves, Gnomes, and Halflings, can all crossbreed. Halflings typically do not retain genetic contributions made from Dwarves or Gnomes due to their significantly shorter life spans and higher fertility rates (adult at 13, 5-6 month gestation, death at 65, twins or triplets not uncommon) "breeding them out". All Goblinoids can breed with each other: Hobgoblins, Goblins, Bullbear/Bugbears, Trolls and even the 'High' Trolls; Huldra, Yotunn, and Hiisi. With zero geographic or cultural barriers all Goblinoids will quickly "melt" into either a novel Troll or Goblin population. High Trolls typically kill lesser Goblinoids for this exact reason. Wood Elves & 'High' Trolls (Huldra, Yotunn, and Hiisi) can breed, but High Elves cannot. Wood Elf and Huldra communities will typically assimilate each other with a single phenotype eventually winning. Dragons can actually only breed with other Draconids (in which case they can breed with ANY Draconid, even a Cockatrice), but Dragon flesh, Dragon Matter, is bioaccumulative; giving the illusion of crossbreeding. With that said, intelligent Dragons 120% absolutely fuck mortals all the time. Dragons are capable of "Gynogenesis": sperm can be used from different species to fertilize an egg without making genetic contributions.
>>96583309Weird mutations in other humanoid races.
>>96573691Everything can breed with everything else, but hybridisation only occurs once. Hybrid species only beget children of the same species as the other parent (or the same hybrid species as themselves if the other parent is of the same species or the species of either of its parents).
>>96584818Lame, I want to fuck the elves.
>>96584807>entirely equivalentNot exactly. That works for two species with the same die if you dislike randomizing the target number, but when they have different dice it's entirely possible for the larger of the two to roll numbers the other can't. So two elves have a less than 10% chance to conceive but an elf and goblin are much, much less likely to manage some short green elves.
>>96586038>it's entirely possible for the larger of the two to roll numbers the other can'tThat's also why I thought it might be neat but then I actually worked the probability out. Clearly you didn't bother to double check the probabilities despite me pointing it out, but I'll be nice despite you being a mathlet and work out the probabilities for you:For 1dA and 1dB with A<= B, the probability of any single outcome is 1/(A*B) and the total number of different outcomes is A*B. Impregnation occurs when the numbers match, there are only A possible ways this can occur and A* 1/(A*B) = 1/B.To give alternative reasoning: for every number you can roll on the 1dA, there exists a number on the 1dB that can match it. The chance of rolling that number is 1/B.
>>96586243I get that the dice share numbers, that's why it happens on a match and yes a d12 has four sides that could match a d4, but you also get times where say a captured elf cannot be impregnated by the goblins that took her despite goblins being fast breeders amongst themselves. I suspect it may be an "all squares are rectangles" issue based on which die we assume is setting the target number for the other. If we say the female die is setting the target for the male we get the earlier "elf rolled an 11 and goblins can't do better than 4" but reversing the genders gives us "goblin rolled a 4 so her elf boyfriend has the same 8.3% chance he would with another elf"
>>96587157The probability of the event does not depend on the order you choose to roll the dice. Sure, you can assign different narrative significance to a particular order but the probability is exactly the same. It's clear that you aren't able to understand the mathematics, so I'll explain it by your own example.Say a goblin has a d4 and an elf has a d12. 2/3 of the time the elf will roll something that the goblin can't match. 1/3 of the time the goblin has a 1/4 chance to match it. Therefore, 1/3 * 1/4 = 1/12. Let's say it's the other way around. The goblin can roll any number in 1-4, the elf then has a 1/12 chance of matching that number. Same thing. The probably is always determined by the higher dice, order doesn't matter and the smaller dice doesn't matter either.
>>96587669How would you do it then? So that fast breeding races get/cause pregnancy more often and slow breeding races less often? And that some days two very different races just aren't going to make a baby no matter how they try?
>>96587882I was going to give a detailed suggestion for this but I got caught up analyzing the dice because I wanted to understand the exact numbers. Based off your description it sounds like the actual situation you want is: Low dice are more likely to fall pregnant than high dice (fast breeding), Highest odds of falling pregnant with someone when the dice are the same. In order to achieve that using a similar idea you could do 3dA = 3dB. I did some dice simulations and as far as I could tell that works as described though I can't give you a formula for the probabilities. 2dA = 2dB doesn't work super well for some reason.
>>96590595So aiming for an average instead of the same rolls? I'd imagine it drops all of the impregnation probabilities somewhat, with drastic effects between those using different dice. I had considered other ideas waiting on your reply, but I do like the 3dX and it affords further granularity between different races as you can assign different mixes of dice, or have traits to alter results for an individual such as low fertility adding an extra die to skew results while a fertility blessing may give "roll an extra die from your pool and pick three to total" for the next day or moon cycle or whatever.
>>96590831No. Not aiming for the average, rolling the same number. 3dA = 3dB, getting the same total number on both rolls. >>96587882If you want to go for something like this, the easiest way to control the odds is by shifting the range, either by adding a number to the larger dice, or subtracting from the lower dice.I suppose one benefit to this is that you can start adding extra dice pool mechanics on top as you are suggesting. I do like the idea of a fertility blessing being 4dA choose 3 dice, just from a gameplay perspective. Though I don't know how that actually affects the odds.
>>96590909>average vs totalThat's my bad, mistyped what I meant. But yes, same total for both rolls, just that at 3dX you're going to be looking around the middle of your bellcurve most of the time, which will change the odds greatly between different die types but at least it's not "all dice must have the same face">range and mechanicsI think I'd prefer to keep flat modifiers to various traits, but it does offer a simpler path than trying to mix and match die pools for every race.As for the odds, it would be a bigger help to already fast breeding species but slower ones may take whatever they can get. Or there could be a curse version for cultists to lay on an unfortunate candidate. Fiendish Fecundity, target and all partners until next dawn roll an extra 3d6; as many dice as needed may be used or discarded to create a match but if any roll ever includes three sixes then impregnation is automatic and comes to term within 1d10 minutes with severe risk to the mother. This child is a half-fiend, or full demon if both rolls had three or more sixes. In other cases of impregnation the pregnancy is normal and child has only minor fiendish traits.
>>96590985Trying to find any suitable match up on 6 dice sounds like it would take a lot of time at the table. I was already a bit worried at 4 choose 3 but there's a fun element in being able to take out a dice to achieve success. 6 dice sounds like it would waste time.For flat modifiers it's obvious that the ideal fertility occurs when the bell curves overlap with each other, which happens when you add 1.5(B-A) to 3dA.
>>96583526This. You're your mother's race like in Elder Scrolls and Granblue.
>>96591186It's the same in Mystara as well. Half elves are only there because of a curse
>>96581587So what happens if I have sex with the Voices in my head? How do I make magnetic field babies?
