In case you haven’t seen yet, circuit will be trumped by any other tertiary, so you’ll need another circuit dragon to breed him with. If you haven’t gotten one by the time he’s ready to breed, lemme know? I’ll prob have someone I can send over. :)
Oh, good to know! D: So is circuit the “weakest” tertiary? A recessive gene? Damn, I should have expected that :’D thanks!
There really should be more officially about this, shouldn’t there? :P
Circuit is definitely the weakest tertiary. There’s no “recessiveness” sort of genetics in this game, where a dragon can “carry” a gene but not show it. What you see is what that dragon can pass on, and what shows up in the kids is kind of a RNG battle royale between what the two parents have.
In general, the weakest genes in the prim/sec/tert spots are iridescent/shimmer/circuit. I haven’t worked out the math here, but if you want to reliably get any of those three traits, it’s a good idea for both parents to have them. You DO have a chance to get a circuit if you breed a circuit to a crackle or an underbelly or heck, even a basic, but it’s a low chance. I’m pretty sure that there’s a hierarchy of all traits, but I haven’t really worked out the math of, say, how tiger vs. clown goes down. (oooh, here’s a slightly-old [no crackle, for instance] chart!)
In general, though, at the very least it’s good for you to breed tri-gened dragons to tri-gened dragons (or, dual-gened dragons to dragons with genes in the same slots), so that you don’t have any chance of “losing” a trait in the kiddos. That is, unless you like the look of basic in any particular slots, of course.
If you’re planning to breed for a particular trait or combination of traits (or heck, even if you just are bored), I’d suggest playing with the Foresee Progeny tool in the Scrying Workshop. You can plug in your dragons and see what the chances are of you getting what you want. Also useful when you’re poking around the AH for a mate for someone. :)
Oh! And also, again in case you haven’t run into it: there is an incest ban. ;P Two dragons that are related…whut, like up to 5 generations back cannot breed. The Assay Bloodline tool in the Workshop will let you know if you’re going to run into this problem (praise all the dragon gods for that…the Workshop is a new thing…we used to have to just try to keep track or guess.) So, unless you like charting out family trees, you’ll probably find yourself on the AH a lot trying to find a mate for someone you want to keep but who…is related to everyone else. :P
Hope this helps! Let me know if you have any other questions.
