The symbols are good to keep track of one IV, but what if they have more than 1 flawless IV?? For instance, x pokemon has 31/x/x/31/31/31 and y pokemon has x/31/x/31/31/31.

You have six symbols to mark each of your flawless IVs. In your case Pokemon X would be marked as ● ♥♦ while Pokemon Y would be marked as ▲ ♥♦. It's fairly intuitive when you select to mark a Pokemon.

Oh. I didn't know that you were able to give MORE THAN ONE mark to a pokemon. That clears up a lot of confusion.
 
2 things I would like to ask.

1) I'm trying to breed a good riolu. I caught a took a few of them with decent IVs from the safari, and safari ditto with some of the IVs i want. But the thing is, im not getting eggs. I always thought ditto can breed with anything. The guy in front of the day-care said that the two pokes rather play with others than with each other. Does that actually mean that those two will not produce eggs no matter how long I wait, or am i being just to impatient? I'm asking this because I was breeding Phantump before and they still produced eggs, even when the guy in the daycare said that my phantump and ditto didn't like one another.

2) What is the best tactic for breeding pokemon with egg moves? Say for example, I think as of now, Mamoswine can only get rocks via breeding (with onix i think). Should I aim first to get a swinub with the IVs i want, and then breed it with an onix with good IVs to get rocks?

Riolu cannot breed as it is a baby Pokemon. Evolve it into Lucario, then breed.

You want to breed on egg moves first. Breeding a flawless Pokemon then breeding on egg moves is just about twice the effort.
 
im trying to find a ditto fs so i can find something crazy pleese help ill offer a metal coat for help
 
On my first breeding project, got to two, 5-perfect Brelooms relatively quickly: x/31/31/31/31/31 (female) and 31/31/31/31/31/x (male). After a few eggs from this couple using Everstone and Destiny Knot, I got a 6-perfect male, and swapped him into the day care. Two eggs later (still in the 5-stat eggs), I got another 6-perfect (male).

After super training and doing some other things, I just got around to hatching the rest of my eggs from the 5-perfect/6-perfect couple (couldn't be more than 9-11 eggs total), and found a third 6-perfect male Shroomish.

My experience is anecdotal, but judging from the frequency of 6-perfects reported in the thread, are we quite sure the chance of getting a 6-perfect egg from two, 5-perfect parents is only around 1/100 ~ 1/200??

Mathematically speaking, yes, 1/100~1/200 is correct when using two 5-perfect parents. Its crazy that you're getting so many good eggs, but not impossible.
 
I'm trying to breed a Spritzee with Wish as an egg move and Aroma Veil. I've got a wrong nature male spritzee with Wish, and a female wrong nature spriztee with Aroma Veil, the HA I want. Do you think its best to breed a decent IV'ed Spritzee without the Aroma Veil ability and then breed that in at the end? I know its a lot easier to breed in egg moves right at the beginning of your breeding chain, but I'm not sure about abilities. I's also got to think about nature (want calm) and also preferably a 0 speed IV for trick room fun.
Does anyone have any tips? Would you farm for a 0 speed IV ditto (Pretty sure I have one lying around) or a 0 speed iv Spritzee to begin with and power item it down?

Urgh, its tough, but I'm determined to breed it!
 
This is very helpful! I was RNG like crazy in BW, but this gen seems much kinder as far as breeding goes. I'm about to breed a nf/f gligar for breeding purposes (got to get that quick attack onto Pinsir :-) ). Currently i have x5 Female and a x4 Male with upper 20s in the other 2 stats. I don't care about the nature of the Gligar since it will be a male to just pass off an egg move and good IVs. Should I run a destiny knot on the female and a the necessary power item for the good IV I want from the male?

I strongly belive that the probability is 1/96, not 1/128 as stated in the OP, something I tried to argue in this post. It is still a low probability, but at least it's not in the 1/100 ~ 1/200 range.

aaaaa I completely missed your post Eiff. I'll get to looking over your calcs and implementing them soon.

I put together complete probability tables for all possible inheritances (with and without power items) using the same method as Eiff. Ill post it later tonight.
 
Are we sure Destiny Knot only ever passes on 5 IVs? Is there no possibility of other new mechanics like, "sometimes pass on extra IVs regardless of what's going on," or, "when breeding, give the player bonus chance at 31 IVs," or anything like that?

Other people have tried over 96 times and not gotten 6-perfects? EDIT: Going over the thread more carefully, it's filled with a lot more tears about not getting these than my initial impression...

I can't have hatched more than 50-70 eggs in XY total, and I already have 3x 6-perfect Shroomish, 3x 5-perfect Shroomish and 6x 5-perfect Mawile of the right stat already. (Although I guess the odds of getting a 5-perfect now are extremely high...)

I meant a nod to your 1/96 calculation with "around 1/100". I should have been specific.


By the way, I hadn't seen this in the thread yet, apologies if I missed it:
http://nuggetbridge.com/breeding/pseudo-rng-abuse-for-eggs-in-pokemon-xy/

If I'm reading correctly, apparently the specific IVs that will be passed down and generated are set BEFORE you even place the parents in the day care, allowing you to use "Test" parents to see which IVs will be passed, then load your game to put appropriate parents in, guaranteeing a 5-perfect from 2/3-perfects.

I have to assume there's a separate stream of RNG seeds for the day-care that is restored on Load and isn't affected by other parts of the game requesting RNG?

We are pretty certain that only 5/6 IVs are passed down. The final 1/6 is always a random number, so even with two 6x-flawless parents, there is a small probability that your final child will end up 6x-flawless and a very large probability that your child will only end up 5x-flawless.

The odds of getting a 5x-flawless child with 5x-flawless parents (with the same stats) is 37/192, or just more than 19.27%.

Getting a 6x-flawless child with 5x-flawless parents (with the same stats) is 1/192, but the more you breed the greater the chance that you will eventually end up with a 6x-flawless child eventually:

P-not-flawless(n) = (1-1/192)^n = (191/192)^n
P-flawless(n) = 1 - (191/192)^n
Where n = number of successive eggs with the same parents.
The probability of not-flawless over time is asymptotic to 0%, whereas the probability of flawless over time is asymptotic to 100%

EDIT2: I took the time to calculate 6x with two 5x parents with different imperfect IVs with a Power Item;

[4/5 (chance of non-inherid IV being perfect on both parents) * 1/2 (Correct IV inheritance) * 1/32 (Max IV generated)] + [1/5 (chance of non-inherid IV being potentially imperfect) * 1/32 (Max IV generated)] = 3/160 (~1/53)
Am I reading this right that the best way to get a 6-perfect (say, for breeding into a new egg group) is power item + destiny knot?

Yes, this is correct. Its a slight boost and not terribly large, but it is a boost.

If you care about nature, you will want to stick to Destiny Knot + Everstone, however.

Probability tables as promised. For clarity sake I'm going to reduce it, and keep it in terms of desired outcomes.

Key is as follows:

X = Neither parent has the desired IV

Mom IVs: 1/31/31/31/7/8
Dad IVs: 31/3/31/31/31/9 (Power Weight equipped, HP to be passed down)

Sprocket that is fucking amazing.

Good job, goddamn, will implement into the guide with credit given to you soon.
 
Probability tables as promised. For clarity sake I'm going to reduce it, and keep it in terms of desired outcomes.
Very nice work Sprocket. Did you find and use some kind of formula or did you go through each one by one?

Anyway, this is what I take from the tables: Power Items are only useful when you only want perfect fathers within a egg group, but never if the nature matters.

While I understand the point of "Escaping the 1/24 plateau"-as the OP puts it, you are much more likely to get the desired offspring without going though the detour with Power items.
Just to take one example: you want a 5IV with a correct nature when you have two 4IV parents with different imperfect IVs but correct nature.
Without power item: BBBAA - 13/256 ~ 5.0781%
With Power item detour: PBBBA*BBBBA = (37/320)*(19/192) = 703/61440 ~ 1.1442%
 
Hey!

right, I managed to breed my Gible with outrage; 31/31/31/x/31/31. However, I feel this was complete luck as I have had 3 more boxes full of gibles and nothing the same. Trouble is, I cant remember the rents I used as I was pretty sure I had better come along so I swip-swapped around a lot after that.
I have two possible rents along the lines of X/31/31/31/31/31 and 31/31/31/31/31/X. My question is, am I more likely to breed a 6x with these parents rather than another 31/31/31/X/31/31? Or would you recommend going back to x4 IV's Parents with definately NO perfect SpA IV?

I am confused as I would have thought the 5 IV's were better but Somethings going wrong as I get pokemon with only 2 or 3 perfect IV's; and yes, my parents are definately holding the destiny knot/everstone.

This bastard also takes long to hatch as well, I thought Larvesta was bad :(

Also, I didn't breed in his DW ability; is it going to be useless trying to trade with him without Rough Skin? I suppose it wont be too much trouble breeding it in now if the above parents generate my 31/31/31/X/31/31!

Thanks in advance.

Sorry, I'm still struggling with this. Just can't get it in my head hows best to start; I've got the egg moves/pokeballs and nature I want but I just think its too much to get in a 0 speed IV as well! Any tips would be brill :)

Thats how I interpret Power Item usage as well. Granted there are times where you don't care about nature. I'm not sure how the math works, but the way you state it makes sense.

I did everything by hand, but a formula could be developed. Its pretty straight forward. For example the inheritance spread PBBAA has 5 possible outcomes: BBAA is inherited, BBAn is inherited (x2 chances), BnAA is inherited (x2 chances). (n represents a desired stat that is not inherited, but could come up how you want anyway). So:

BBAA is (1/5) * (1/2)^2 = 1/20, BBAn is 2 * (1/5) * (1/2) * (1/32) = 1/160, BnAA is 2 * (1/5) * (1/2)^2 * (1/32) = 1/320, add them up and you get 19/320

As long as both parents have different IV spreads (X/31/31/31/31/31 and 31/31/31/31/31/x, 4 shared IVs), your chances of a 6x flawless and 5x flawless are the same: 1/96 and 19/192 respectively. The only way to increase these odds is to increase the number of shared IV from 4 to 5.
 
Is there anyway to tell if a Magikarp will end up with Intimidate or Moxie as its ability? I am breeding with an Adamant Ditto with a Female Gyrados w/ intimidate if that helps.

Yes.

If the Mom Pokemon (or non-Ditto Pokemon) does not have its hidden ability, the child will NEVER have its hidden ability.
If the Mom Pokemon (or non-Ditto Pokemon) has a hidden ability, the child has a 60% chance of having its hidden ability.

Since your Gyarados has Intimidate, and not its hidden ability Moxie, you will never receive a Moxie Gyarados child (Or to be specific a Rattled Magikarp).
