Correct. For convenience there's also Nature Mints and Bottle Caps for changing Nature and IVs. Mirror Herb also allows them to learn Egg Moves from another Pokemon of the team on Picnics (the stand in for Daycare breeding)So we no longer have to breed someone with the HA to pass it down? I'm way behind in the meta, as well as from the past gen. I can give an Ability Patch to my mon and I can choose the HA then?
GF in the last couple gens have been adding a lot of QoL items to let you make Pokemon into Battle readies without having to breed them from scratch.
