Single post in All about IVs & IV Breeding (wip, open for questions)

Pokémon's six singular IVs - Health, Attack, Defence, Sp.Atk, Sp.Def and Speed, are determined at the time of the egg's creation. How IV numbers will be generated depends on the three factors: - If Pokémon has parents or not; - If one of the Pokémon's parents hold Destiny Knot; - If User has Master Badge matching one of the Pokémon's type. Terminology used in this section: • 'Inherited IVs' - are IVs offspring received from parents. • 'Randomised IVs' - are IVs generated by the SYSTEM using numbers from 0 to 31. Pokémon without parents Pokémon who are obtained from the Lab, Supplier, by Summoning and other methods where parents are non-existent have all of their six IVs completely randomised. Beside having the corresponding Master Badge to slightly increase randomised IVs, getting such Pokémon with high IVs is purely luck based. Master Badge effects are explained in the 'Part 5: Master Badge'. Default IV Inheritance By default, when breeding any two Pokémon in the DayCare, the offspring inherits three IVs from one parent, another, or mix of both, while the remaining three are randomised. Default inheritance isn't considered an act of IV breeding, therefore breeding methods without Destiny Knot won't be explained. Parent holding Destiny Knot Any parent can hold Destiny Knot and offspring has an equal chance of inheriting five IVs from one parent, another, or mix of both. This means that five singular IVs will have a 50:50% chance to be from one of the parents, while sixth will be randomly generated number from 0 to 31. Be aware that you can't influence which IV will be randomised or inherited. Furthermore, giving both parents Destiny Knot doesn't have any additional impact on IV breeding as Destiny Knot effect doesn't stack.

There are multiple IV breeding methods you can use to acquire desirable IV outcome. Even though this guide will focus on 6IV outcome examples, getting any specific IV numbers and high IVs is possible with these methods. Each method will be explained in detail in separate sections. • Starting from scratch - This method explains how to start with bad IV pokemon pair and eventually achieve perfect IV pair through selective breeding. • Starting with 5 or 6IV Pokémon - This method shows how to quickly achieve perfect IV Pokémon while using same or another species 5 or 6IV Pokémon. • Using +2IV Ditto - Thanks to Ditto's ability to breed with any breedable Pokémon, if you own +2IV one, you could use it to start your IV breeding. • IV Breeding Unown - Explanation of how to achieve specific Unown letter with perfect IVs. See 'Part 4: Special Hunts' for Variant and Genderless IV breeding.
