Pastoria City—To the north of the lake on the eastern side of town (requires Surf)

Held item (100% chance) found on the following Pokémon:

Castform (Trophy Garden)

Yes

The easiest way to get a Mystic Water is by finding the one in Pastoria City. You can reach this item as soon as you’re able to use Surf outside of battle.

Alternatively you can also farm Mystic Waters by taking them as held items from Castform, but this is a bit more complex and not always worth the effort.

Acquiring Mystic Waters

Method 1: Pastoria City (Step-by-Step)

You’ll have access to a quick and easy Mystic Water from Pastoria City as soon as you can use Surf in the overworld.

This requires you to have defeated Pastoria’s Gym Leader Crasher Wake and obtained HM03 from Celestic Town.

Once you’ve taken care of those requirements, Fly to Pastoria City and head southward from the Pokémon Center.

Heading south from Pastoria City’s Pokémon Center.

Continue south past the Berry Plot.

Continuing south through town.

Turn eastward to reach the lake, then use Surf to skim across it to the right.

Head for the northeastern corner of the lake where the ships are anchored, then step onto the land to the north to reach a Poké Ball item.

Method 2: Held Item on Wild Castform (Repeatable)

You can also find Mystic Waters being held by wild Castform.

Castform are only found in the Pokémon Mansion’s Trophy Garden on Route 212. So you’ll need to have visited Pastoria City at least once before you’re able to attempt this.

Finding the Pokémon Mansion

To reach the Pokémon Mansion, Fly to Hearthome City and head south from the Pokémon Center.

Taking the main street south from the Hearthome City Pokémon Center.

When you reach the white picket fences to the south, head eastward.

Turning east and passing the Poké Mart.

Take the south turn by the fisherman NPC standing in the middle of the street’s intersection, then turn west at the Hearthome City sign.

Turning south at the fisherman NPC, then west at the sign.

Travel westward until you reach the two city gates in the southwest corner of town.

Take the gate to the south—this will put you on Route 212.

Leaving Hearthome City via the southwest gate.

Pass through the gate and continue southward on Route 212.

Exiting the gate and entering Route 212.

Continue moving south, hugging the eastern edge when trees start to break up the path. Circle around the ponds you encounter along the way.

Keeping to the right of Route 212 until the first pond.

Head south when the bushes begin to resemble a sort of hedge maze, and eventually you will see the Pokémon Mansion’s gilded front gates and statues.

Head up through the front gates to approach the mansion.

Heading through the gate of the Pokémon Mansion.

Then enter the Pokémon Mansion through the front doors.

Getting Wild Castform to Spawn

Inside the mansion, take a right to enter the eastern corridor.

Taking the right hallway branching off the entrance hall.

Enter the first room to the north, which is Mr. Backlot’s office.

Entering Backlot’s office to the north.

Tip: Save the game before you do anything else.

Inside the room you will find Mr. Backlot standing next to his butler.

If you speak to Mr. Backlot, he will go on a long self-congratulating speech about the rare Pokémon he has in the Trophy Garden. Act impressed to keep him talking.

Inflating Mr. Backlot’s ego.

Eventually Mr. Backlot will mention the latest rare Pokémon that he allegedly saw in the Trophy Garden. The Pokémon he mentions is random and changes once every 24 hours.

However, if you soft reset the game and speak to Mr. Backlot again, you can force the specified Pokémon to change to a different one.

Repeat the soft reset process until Backlot mentions Castform.

Mr. Backlot’s butler will then inform him that the specified Pokémon isn’t actually in the Trophy Garden. After a quick discussion between the two, the butler will leave the room.

Mr. Backlot will continue lying in an attempt to save face.

At this point, the butler will have already snuck out and released the aforementioned Pokémon into the Trophy Garden under Backlot’s orders.

So now you can leave the room and head westward back into the main hall. Then turn north and leave the Pokémon Mansion through the back exit.

Heading out back to the Trophy Garden.

Farming Wild Castform

Enter the Trophy Garden and search through the tall grass for a Castform.

This may take a while, since each random encounter only has a 5% chance of being the Pokémon Mr. Backlot bragged about.

But the good news is that unlike most wild Pokémon you’d steal items from, a wild Castform is guaranteed to be carrying an item.

When you find a wild Castform, either take its Mystic Water by using a stealing move like Thief, or capture the Castform and remove the item that way.

Mystic Water Details and Uses

The in-game description of the Mystic Water.

The Mystic Water is a held item that boosts the power of Water-type attacks by 20%.

This is another in a long line of no-frills type-boosting items like the Miracle Seed and the TwistedSpoon.

Generally, water types best showcase their power with big special moves like Hydro Cannon, Surf, and Hydro Pump.

This means the Pokémon who will get the most out of a Mystic Water is a Pokémon with a high Special Attack stat, such as Kyogre, Slowbro, Blastoise, and Gorebyss.

While the Mystic Water will stretch the damage of Water-type attacks launched by any Pokémon type, it works best on Water-type Pokémon by adding the STAB effect to the overall damage output.

There are items that do a better job of maximizing damage (see: the Life Orb), but they tend to have drawbacks that can complicate battles. The Mystic Water can be a better option as a free boost for your already hard-hitting Water types.
