Pseudo RNG Abuse for Eggs in Pokémon X & Y

Yes, it’s actually happening! The credit for it goes to Japanese players who discovered that IVs of the egg are determined before the parents are even deposited in the Day-Care. Sounds pretty crazy, but believe me, it works!

Prerequisites

In order to be 100% sure about what IVs and from which parent are inherited by the egg, you need to have following things:

  • A pair of Test Parents from any egg group that both have all different IVs. The best way to find them out is to go to the Battle Institute (Lumiose City, Northern Boulevard) as their level will be set to 50 and the results will be very accurate. If you don’t know the exact EV spreads of your pair, just erase them with a Reset Bag. Note that if you don’t have any 31 IVs among your Test Parents, you have a higher chance of spotting a hex flawless spread as the stat that’s not inherited is random. Important: Inheritance can differ for Pokémon with different gender ratio. It’s recommened to use Test Parents with the same gender ratio as the target. Personally, it happened to me only when I’ve been breeding genderless Pokémon, but there were reports of the shakiness for other Pokémon as well.
  • Destiny Knot (2nd floor, Cyllage City Hotel) and Everstone (Geosenge Town, given by a Scientist in leftmost house).
  • A Pokémon with either Flame Body or Magma Armor ability and a Pokémon that can use HM02 Fly (Fletchinder and Talonflame are your best bets as they both and Fly and have Flame Body).
  • A bunch of Pokémon you want to RNG with at least 2/3 perfect IVs. Make sure that the female (or Male if breeding with Ditto) has the desired Ability. There’s a 60% chance that the offspring will inherit mother’s Ability.
  • Access to a decent IV calculator.
  • (optional) Hatching O-Power.

The Process: Practice

  1. Put your Test Parents in the Day-Care. One of them must hold Destiny Knot.
  2. Ride your bike outside the Day-Care until Day-Care Man gets an Egg for you (he’ll be facing down, towards the road).
  3. Take and hatch the Egg.
  4. Go to the Battle Institute (Lumiose city, Northern Boulevard) and take a test. Don’t worry, you don’t have to save your game.
  5. Go to your hatched Pokémon’s Summary and calculate its IVs.
  6. Write down which IVs have been inherited and from which parent.
  7. For future reference, you might want to write down the stats of the hatched Pokémon to save time when RNGing next time.
  8. If you’re satisfied with the inheritance spread you’ve obtained, reset the game and swap the Test Parents with another couple that has perfect IVs matching your inheritance spread (use Everstone to ensure you get the right nature). Hatch the egg and congratulations! You’ve just successfully RNGed a Pokémon in X/Y!
  9. If you didn’t get desired spread, reset your game, repeat Step 2 but instead of getting the Egg from the Day-Care Man, reject it and save the game. Repeat Steps 3-7. In case you didn’t get desired Ability with your final parents, you need to repeat the process.

The Process: Example

My Test Parents are a pair of Sunkern:

sunkern (M)  destiny_knot
Nature: Bold
Stat IV
HP 2
Atk 16
Def 30
SAtk 21
SDef 9
Spe 2

sunkern (F)
Nature: Serious
Stat IV
HP 4
Atk 11
Def 12
SAtk 0
SDef 26
Spe 7

The hatched Sunkern has Hardy Nature and following stats at level 50: 92/43/49/50/48/36. I calculate IVs and get result of:

sunkern
Nature: Hardy
Stat IV
HP 4
Atk 16
Def 30
SAtk 31
SDef 26
Spe 2

I try to match them and instead of exact IVs, I put X for the random non-inherited IV, M for Male’s IV and F for Female’s IV and get: F/M/M/X/F/M I search among all the Pokémon I’d like to breed for a Female with 31 IVs in HP and Special Defense and a Male with 31 IVs in Attack, Defense and Speed. I reset the game and take back my Sunkern couple. I go to the PC and find a 31/x/x/31/31/31 Bold Female Intimidate Mawile and an x/31/31/31/x/31/ Adamant Male Floatzel. Since I want to have an Adamant Mawile, I put my Everstone on Floatzel and Destiny Knot on Mawile. A 31/31/31/31/31/31 Adamant Intimidate Mawile is my goal.

floatzel (M)  everstone
Nature: Adamant
Stat IV
HP x
Atk 31
Def 31
SAtk x
SDef x
Spe 31

mawile (F)  destiny_knot
Nature: Bold
Stat IV
HP 31
Atk x
Def x
SAtk x
SDef 31
Spe x

I ride until I get an egg from Day-Care Man, I hatch it, check the Ability and since it’s the desired Intimidate, I go to the Judge. He says that my Mawile’s overall potential is outstanding and its HP as well as its Atk, Def, SpAtk, SpDef and Speed “simply can’t be beat!” which means all its IVs are 31.

mawile
Nature: Adamant
Stat IV
HP 31
Atk 31
Def 31
SAtk 31
SDef 31
Spe 31

    Ok, let me clarify:
     
    Wneh you save the game, the game saves IVs of the next egg that’s going to be taken whether it’s already generated and held by Day-Care Man or is to be generated in the future. The following eggs are not saved and are always random as they are generated when you’re taking the first egg (or right after, doesn’t really matter at that point and with the tools we have at the moment).

    I’d show it on an eggsample (terrible puns’ day, ohohoho), but it’s basically what Mikewando did.

  2. Bopper says:

    Alright I’m actually a bit confused about something here. Could somebody explain to me the benefits of this method of hatching eggs over just getting the eggs in general? Because regardless, you’re going to end up with that IV inheritance from that egg, so why not get that and then some? I actually want to hear how this could he beneficial over regular IV breeding. You could argue that something like rotom might benefit, but why not just keep the rotom-ditto in the daycare in there until you get the right IV Inheritance as you would with the abyss meathod?

    What I’m thinking is that that next egg is set at the moment you accept or reject an egg.  So if you were to repeat your third scenario a few times I don’t think the second egg would be consistently the same.

    It is consistent, but I can now see why eggs past the first one aren’t helpful for the purposes of abusing the RNG because…
     

    The following eggs […] are generated when you’re taking the first egg.

    The N+1th egg is generated based on the parents of the Nth egg and whether you accepted or rejected it. To illustrate…

    Saved
    Put Female A holding nothing and Male X holding Destiny Knot in daycare
    Got egg
    Hatched egg
    Result: Lax Male with F/M/5/F/M/M inheritence
    Got egg
    Hatched egg
    Result: Lonely Female M/F/25/F/M/F inheritence
    Reset

    Hatched egg
    Result: Lax Male with F/M/5/F/M/M inheritence

    Put Female A holding nothing and Male X holding Destiny Knot in daycare

    Hatched egg
    Result: Serious Female M/F/M/13/F/M inheritence
    [/spoilers]
    Basically the same parents and the same decisions will always yield the same chain of eggs, but you can’t swap out parents past the first egg. The reason the inheritence for the first egg remains the same regardless of which parents are used is because for any parents you use, the previous parents and whether or not you accepted or rejected that egg remains constant. This is surprisingly difficult to explain, but I think I understand what’s going on now.

    @Bopper

    If you have a lot of quad/quint-flawless Pokémon for parents this is great because the Rotom thing for instance, or if you found something that you just want to breed quickly and be done with, like something in the friend safari where you have 2-3 good IV’s guaranteed. That’s where you’ll save your time. If you already have several quad/quint flaw things that you are using to breed chances are this method will only shave 5 minutes off your breeding time, if that.

    It could also be used to ensure that you are picking up a certain IV (such as a 0 in speed) while making sure that you get your nature/ability via everstone, and few other IV’s from the parent. I did this with my Amoonguss to make sure that I got a 0 in speed while 31 in relevant stats and it took me no more than 10 min to hatch 3 perfect eggs. Although when I tried to breed another one last night for somebody else, it took me ~32 eggs to get 31/x/31/31/31/0.

    Alright, thanks araluen. That makes sense to me, looks like I’ll be testing this out tonight.

    It will also make Hidden Power IVs easier to breed. Even if you have parents that are prettyclose

  11. mattj says:

    It will also make Hidden Power IVs easier to breed. Even if you have parents that are pretty close you’d have to be dang lucky to get the odds and evens just like you need. But this way you can say “Oh. I just need to put this parent with that and I’ll get O/E/O/O/E/O”.

  12. Otterz says:

    So if we don’t have a big variety of parents yet (Me) this method is not useful?
     
     

    It will also make Hidden Power IVs easier to breed. 

     
    Are Hidden Powers still prominent? I personally haven’t seen any since the release of X/Y and they miss even more KOs now.

  14. mattj says:

    I think their relative rarity has more to do with the lack of traditional rng abuse and difficulty of obtaining Dittos with significant and various 31s and 30s. HP will still 1HKO many common threats with 4X weaknesses, which will still be useful. We just won’t be able to fling them around everywhere like we used to and take as big of chunks out of everything.

    It isn’t as useful, you can save yourself from having lots of excess eggs, in looking for a particular inheritance, but just starts off you’re better off just randomly breeding till you have 3-4 IV parents.

    Hidden Powers, not really sure…if you can hit a quad weak Pokemon (like say HP Ice on a Salamence), probably be worth it still. Otherwise assuming an attack isn’t nve, may as well just use a stronger STAB attack for about the same damage.

  18. araluen7 says:

    Otterz, it’s still useful to you, just not in the way it is for me and bopper. In your situation you can go through maybe like 5-6 resets without finding a spread you want, whereas I will always be able to find a useful spread for breeding whatever (unless I swing the unlucky random Hp) because of how many useful parents I have in various groups. But you can use it say if you had a 31/31/31/x/x/x and a x/x/x/31/31/31 and wanted to pinpoint a spread that nets you quint-flaw. Just, with the little amount of parents you have, that’s pretty much all you’re limited to, since if you got a F/F/R/M/M/M, well that spread may be x/x/R/x/x/x instead of 31’s.

    Like, yeah this strategy is cool and saves time (somewhat) but you’re not being forced to do it. Idk about Gonzo or the other breeders we have here, but I hardly use this at all, mainly because I like to multitask and hatch in bulk while studying or Core Training other Pokémon. And also if you were to breed for HP this would be the way to do it, but I think it’d be better to wait for the rules to be announced before saying I’m deff going to need a HP Flying on this poke and then realize that you don’t, or he’s not even allowed. Just my two cents based on complaints about this I’ve seen across several forums.

    will it still work if i do M/M/M/M/F/F? or will one of the IV’s still be randomly generated instead of inherited?
    please let me know asap! thank you

    Destiny Knot only gives 5 IV, one will always be random, but if it happens to be 31 it will stay locked into 31.

    can someone confirm the process for me:
    1) i have a male Eevee M/M/M/X/X/X and female Eevee X/X/X/X/F/F
    2) hatch an egg and check what the baby inherited
    3) if the baby inherit 5 IV’s, soft+reset then reject the egg
    4) then put in ANY 2 completely different pkmn that are breedable but are also M/M/M/?/F/F
    5) the new baby pokemon will still receive the last rejected egg’s IV’s spread?

    I managed to get a 31/31/31/31/31/x Sassy Larvitar with relative ease last night, and I’m now trying to get the right inheritance spread for either a Marril or Togepi, because my parents in both cases stubbornly pass on their useless 31 SpA/Atk over a better stat when breeding traditionally.

    I think I might be doing something wrong when trying to reroll the random stat though, because after 3 tries it keeps coming out as defense. I’m not really sure what to do – what I gather from Mikewando’s post is that I need to accept and hatch an egg from another set of parents before I can go back to my Magikarp and have the inheritance spread changed. Can someone who has had a little more practise confirm this for me?
