|Moon Stone Acquisition Methods|
|1||Eterna City—On a small patch of land in a pond at the northeast corner of town (requires Surf) (hidden)||No|
|2||Mt. Coronet—On a boulder at the northeastern section of the summit (requires Rock Climb, Strength, and Surf) (hidden)||No|
|3||Held item (5% chance) found on the following wild Pokémon:
|4||The Underground—Potential treasure found in the mining minigame||Yes|
The easiest way to get a Moon Stone is to find the one in Eterna City after getting Surf. Although once you have access to Mt. Coronet it gets a lot easier to farm Moon Stones as held items from wild Clefairy.
You can also pick up Moon Stones earlier in the game by digging them out of the Underground, but this method usually takes a lot more time.
Acquiring Moon Stones
Method 1: Eterna City (Step-by-Step)
Once you’re able to use Surf outside of battle, you’ll have access to an easy Moon Stone in Eterna City.
To reach it, Fly to Eterna City and head north up the street from the Pokémon Center. Then take a right at the corner to follow along with the road.
Move across the hill containing Eterna City’s legendary statue.
Pass the bike racks, then head up and use Surf at the pond.
Surf up to the tiny patch of terrain at the northeastern corner of the pond.
There is a hidden Moon Stone on the right-hand tile.
Just face this tile and press A to acquire the Moon Stone.
Method 2: Mt. Coronet (Step-by-Step)
The only other Moon Stone in the overworld is found at the summit of Mt. Coronet. To reach it, you will need Pokémon with the following Hidden Moves:
- Rock Climb
The entrance to Mt. Coronet that you want to use is northeast of Oreburgh City. So Fly to the Oreburgh Pokémon Center and head north along the main road.
Take the stairs at the northern entrance to leave the city for Route 207.
Go down the small staircase leading to a pit, where there is a muddy slope in the middle of the north wall.
Ride your Bicycle in fourth gear to make it up the slope.
Take an immediate right into the canyon by the Honey Tree.
Travel all the way to the east until you come to Mt. Coronet’s entrance. Head inside.
Once you’re inside, use Surf to cross the small lake to the north.
On the other side, use Rock Climb on the rocky wall and head upstairs.
In the next area you’ll want to go north and take the left turn, ignoring the staircase.
Turn south when you’re able, and use Strength on the boulder in your path to push it southward.
Push the boulder until you can head up the staircase and travel north along the elevated terrain.
Cross the bridge at the end.
Then descend the nearby staircase, pass under the bridge you just crossed, and climb the two staircases to the north.
Cross another long bridge to the east, then circle around to pass under it.
Then climb the stairs in the northwest corner of this section of the cave.
Exit the area through the hole behind the cave painting that Team Galactic broke.
In the next area, ascend the two staircases in the next chamber.
Now just head up the big staircase to the north.
Head up and then turn left to follow the pathway.
Then turn southward and travel down the hallway to find an exit out of the cave.
Outside, head east along either path.
Turn northward and follow the path all the way up.
Use Rock Climb on the rocky wall at the end of the path (just once).
There is another rocky part of the wall above this one, but ignore that. Instead, take a left and then climb the first staircase you see.
Move south through the tall grass here, then circle back around to the north to enter the next cave entrance.
Inside the cave again, use Rock Climb on the rocky wall in front of you.
Then move around the breakable rocks and head northeast.
Go eastward and climb down the next staircase.
Head east on the lower level.
Go through the exit at the end of this pathway.
You’re now at the summit of Mt. Coronet.
From here just head north, passing the staircase to your left.
Walk along the narrow ridge, then turn left to approach a rock sitting in the middle of the tall grass at a dead end.
The Moon Stone is hidden on this rock—just face the rock and Press A to pick it up.
Method 3: Held Item on Wild Pokémon (Repeatable)
Yet another way to obtain Moon Stones is by taking them from wild Cleffa, Clefairy, or Lunatone.
Of these Pokémon, Cleffa and Clefairy are far easier to find (Lunatone requires you to play the game on a DS or DS Lite with Pokémon Sapphire in the GBA slot).
These are still somewhat troublesome Pokémon, however.
Because they can only be found in the Morning (4:00 am to 9:59 am) and at Night (8:00 pm to 3:59 am) in Mt. Coronet, or in the Trophy Garden after Mr. Backlot mentions them.
Cleffa and Clefairy also have a low encounter rate.
And since each wild Cleffa/Clefairy has only a 5% chance of carrying a Moon Stone, this can be a long and tedious process.
But you can greatly speed up the process with an optimized held item farming team.
These special teams use Pokémon with the Abilities Frisk and Compoundeyes to increase the odds of finding items and to identify any items being held.
If you’re using an item-farming team, the Compoundeyes Ability will raise the odds of a Clefairy or Cleffa having a Moon Stone from 5% to 20%.
Frisk will also alert you to whether your foe is holding a held item immediately upon entering a battle.
After discovering a Cleffa or Clefairy with a Moon Stone, you can use a stealing move (like Thief or Trick) or you can catch the Pokémon to obtain the item.
Then you can end the battle however you prefer—you will keep the Moon Stone even if you flee.
Method 4: The Underground (Repeatable)
You can get Moon Stones much sooner if you commit to searching in the Underground for one.
But this is a highly unreliable method and can take several hours of playing the mining minigame to produce results. But if you need one earlier in the game, this is the way to go.
To start searching for Moon Stones, dig down to the Underground by using the Explorer Kit, which you will receive from the Underground Man in Eterna City.
When you have control of your character, head for one of the glittering areas shown on the map.
Tap the touch screen to sense hidden treasures lodged inside bulging walls. These spots will sparkle when your sensor passes over them.
Walk up to one of these spots and Press A.
Digging into bulging walls will begin a minigame.
Alternate between your hammer and your pickaxe to dig as many treasures out of the wall as possible before the wall comes crashing down from the repeated banging.
- The hammer breaks more rocks and dirt per hit, but causes the minigame to end more quickly.
- The pickaxe is weaker, but more precise and less damaging to the wall.
Every time you mine a new spot in the Underground, there is only a 20% chance that a non-sphere item will be hidden beneath the rocks and dirt.
But there are close to 50 different non-sphere item types that can be uncovered.
Because the odds of finding a Moon Stone in a single minigame are pretty low, you can expect to spend a while searching for one.
Tip: Remember to send your items aboveground by selecting them in the Treasures sub-menu.
