What happens if say i have two 4 31 IV Lucario and breed them with the power items in the stats they lack

Just say you had a 6IV Ditto holding a destiny knot, and another 6IV Pokémon holding a power brace. You're still guaranteed to get a 5IV child, but Attack will always be p***ed down from that parent. I would say just use everstone so you get a set nature.

What happens if you combine a power item with destiny knot?

Really helpful, but for the egg move, can you add some information i had to find somewhere else? basically just that they need to be the exact same mon to p*** egg move between parents, and that gender doesnt matter, just throw em at the nursery.

Hyper trained IVs don’t p*** down through breeding either.

Thank you! Fixed the article.

It's not flash fire that reduces time for egg hatching. It's flame body or magma armour
