Specifically, post-game. I'm making my way through Poni Grove and onwards to Poni Coast, etc. (which is opened up after beating the Elite Four).
The only place I can see to heal is the Pokecenter all the way back in Seafolk Village. I can fly there on Charizard but depending on how far I am, can't fly all the way back...
So are there some characters in Poni Plains/Meadow/Coast/Gauntlet that will heal up your Pokemon?
(Not sure anyone else will be able to answer this yet since it's very late game, but throwing it out there just in case.)
