How many IVs should each parent have for the destiny knot to become more effective?

For example:DAD31/22/25/27/31/31MUM31/4/25/27/31/31I’d be guaranteed a 2IV Pokemon with a 1/31 chance of a 3IV.

But would’t it be better if I breed these without the destiny knot in hope for a Pokemon with some max IVs that don’t match up with one of the parents and switch them out then use the destiny knot?

To keep the list concise, I’m assuming both parents have the same number of perfect Roman numeral 4s (and the perfects are in the same stats) and not looking at every possible combination.

1 perfectThe perfect Roman numeral 4 has a 1/2 chance of passing down. 3 are guaranteed to be random, and the remaining 2 or 3 are guaranteed to be imperfect. Average: 19/32 perfectsWith destiny knot: You’re guaranteed to get one random Roman numeral 4 with a 1/32 chance of being perfect. There’s a 1/6 chance that the random happens to be the parent’s perfect one, so you get 1 perfect the other 5/6 of the time. Average: 83/96 perfects

So if your parents already have perfect Roman numeral 4s, and you can use nothing or a destiny knot, then you shouldstart using destiny knot immediately. However, this assumes you can’t use any other items, such as power items.

With power item: You’re guaranteed 1 perfect, 2 imperfects, and 3 randoms. Average: 35/32 perfects

2 perfectsWith destiny knot: There’s a 1/3 chance that the random Roman numeral 4 is one of the parent’s perfects, so only the other perfect one gets passed down. The other 2/3 of the time, you get 2 perfects and 1 random. Average: 163/96 perfectsWith power item: You’re still guaranteed 1 perfect and 3 randoms. There’s a 2/5 chance that the other perfect Roman numeral 4 passes down. Average: 239/160 perfects

So use nothing for parents with 0 perfect Roman numeral 4s, a power item for 1 perfect, and a destiny knot for any more perfects. (though definitely consider the fact that this answer has at least a 1/4 chance of being wrong)

Because the knot makes the offspring inherit 5 stats out of six, the chances for a new perfect stat are slightly lower. However, the offspring with a new perfect stat will likely have more perfect stats overall than if you don’t use the knot.

If you can, I would use a stat boosting item on one parent to guarantee the passing down of a specific stat and the everstone one the other parent to keep the nature, then save the destiny knot for later.

Here are some crunched numbers:If you use the knot, each egg has

Using the knot, you would need ~64 eggs to gain a new perfect stat, but the Pokémon to hatch with a new stat would still have the three original stats. Each egg is guaranteed at least two stats.

Using a stat boosting item without the knot is a good alternative because of the higher chance of more stats while keeping the one in twenty chance of a new stat. After you have four ivs on a parent I would add in the destiny knot. This is because you cannot inherit four perfect stats from the parents without it. Also, do you specifically want all 6 ivs or just 5? Taking the last step to six ivs takes an annoyingly long time and is generally not worth it unless you are using both attack and special attack.Good luck with the breeding.
