There are a number of ways you can get rid of this:
Talk to Ness’ mother (either by telephone or in person) Talk to Dr. Saturn in Saturn Valley Visit any “Your Sanctuary” Use the Instant Revitalizing Device in Winters and Dungeon Man Go to the hot springs in Saturn Valley or Tenda Village
What is Homesickness?
Homesickness is an ailment that has a small chance to afflict Ness at any point in your playthrough. Once Ness is homesick, he’ll begin to miss turns in battle; instead he’ll spend turns reminiscing about his mother & being back at home. If not treated, then the ailment will get worse over time, and Ness will begin to miss his turns more frequently. Thankfully it has such a small chance of happening that it’s not a big worry for most of the game. And Homesickness has a 0% chance of happening at all up to level 15 & after level 76. We’ve prepared a handy table to show just how rare homesickness truly is in Earthbound:
Curing Homesick via Ness’ Mother (Best Method)
By far the easiest way to cure Homesickness is to call Ness’s mother or go back to his hometown and see her in person. She’ll also call his Receiver phone shortly after he starts to feel homesick, to remind him to call home. This initial call won’t cure homesickness – but it’s a good reminder for newer players who may be unsure of what homesickness even is.
Other Cures For Homesick
All of these are viable ways to help Ness shake off Homesickness – so it really depends which method(s) are most practical for you when you’re first afflicted.
Visiting Dr. Saturn
Another method is to visit Dr. Saturn at the makeshift hospital in Saturn Valley. Dr. Saturn is found in one of the bottom houses in the villages, and is distinguished by the fact he’s hiding in a bin. He’ll heal Ness and the party free of charge – which includes all ailments like homesickness.
Visiting “Your Sanctuary”
Visiting any “Your Sanctuary” will also grant the party with a free heal, which includes curing homesickness. There’s 8 of these in total dotted around the world of Earthbound. And each one helps Ness further “connect” with his childhood. The locations for these are:
Onett Happy Happy Village Saturn Valley Winters Fourside Dalaam Tenda Village Lost Underworld
Instant Revitalizing Machine
The Instant Revitalizing Machine located in Dr. Andonuts’s laboratory in Winters will also heal the homesick ailment, since it completely cures anyone who uses it – completely free of charge. Later in the game another one of these machines is found inside Dungeon Man.
Hot Springs
Finally, you can cure homesickness by using the pink hot springs in Saturn Village and Tenda Village. These are completely free to use and will fully restore the party’s HP, PP, and cure all status ailments.
