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

    I swear this game makes sure you inherit the attacking stat you don’t need. I’ve spent 4+ hours trying this method, and I keep getting Attack stat inheritence while breeding my Special Attackers, and getting Special Attack going for my Mawile.

    I just make more 5IV pokemon then.  You must have some completed 5 IV special attackers, so just use them to breed another 5 IV one then trade it out for something you want/need.  I have 3 timid 5 IV Larvestas sitting around right now because of this exact thing.

    My test parents are Magikarp, and the only Special Attacker I’ve completed is a Froakie, so I haven’t done so since I have no idea if it will work due to the gender ratios. I really don’t have a lot of free time to be experimenting with this stuff. :/

    I have a question. If I test with a couple of parents.

    Then I got the IV Spread and see that I need a male with an IV31 on Special Attack for example.

    Can I go quickly to the safari, catch a male with this Special Attack IV31 and get exactly the same spread the next time I submit a couple ?

    EDIT: Seems the answer is yes ^^

    What about shinies and masuda method? Does this work with that?

    I’m new to RNGing so forgive my ignorance, but why are the Atk, Def, and Spe attributed to the male sunkern when the childs Atk, Def, and Spe are not the same as the males?

    Daddy’s Atk, Def, and Speed IVs are 16, 30, and 2 respectively. Baby’s Atk, Def, and Speed IVs are 16, 30, and 2. So yes, they’re the same. I recommend reading the article again. I think you might have read it wrong the first time you read it.

    Wow, RNG even in 6th gen? That’s astounding! It sounds complicated though… I don’t really like the idea of going to the Battle Institute and intentionally losing the battle, either B|…
