Where To Get TM18 Rain Dance in Pokémon Crystal

TM18 Rain Dance
#	Location	Repeatable?
1	Azalea Town’s Slowpoke Well. Found in the deepest level (B2F) of the cave. Strength and Surf are required to reach it.	No
2	Celadon City Dept. Store, 3F. Sold by the NPC behind the counter for 2000 PokéDollars.	Yes

There are two ways to get TM18 Rain Dance in Pokémon Crystal:

Method #1: You’ll find one copy of TM18 Rain Dance from the second basement (B2F) of the Slowpoke Well near Azalea Town. This area can only be accessed by using Surf to traverse an underground lake, and by using Strength to remove some boulders blocking the road to TM18.

Method #2: You can buy TM18 Rain Dance from the TM Shop in Celadon City’s Dept. Store, 3F. It costs 2,000 PokéDollars, and you can get multiple copies.

Celadon City is in Kanto, so you’ll have to conquer the Johto League and get the S.S. Ticket before you can go buy the Rain Dance TM.

Prerequisites

The earliest point when you can get TM18 Rain Dance is at the bottom of Slowpoke Well, which you liberate from Team Rocket control early on in the game.

That said, you must traverse an underground lake with Surf and move some boulders with Strength to reach TM18. In other words, you can’t get this TM the first time you visit.

Instead, here’s what you’d need:

Get HM03 Surf at the Ecruteak City Dance Theater and teach it to a Pokémon.
Defeat Gym Leader Morty in Ecruteak Gym so your Pokémon can use Surf outside of battle.
Get HM04 Strength at Olivine Café in Olivine City and teach it to a Pokémon.
Defeat Gym Leader Whitney in Goldenrod Gym so your Pokémon can use Strength outside of battle.

So the earliest point when you can get TM18 Rain Dance is once you’ve reached Olivine City.

Method #1: From Slowpoke Well (B2F)

Step 1: Find the Slowpoke Well on the eastern end of Azalea Town, close to Route 33.

TM18 Rain Dance Details + Uses

Rain Dance Move Details
Type	Water
Category	Status
Effect	Summons rain for five turns. Rainfall empowers Water-type moves by 50% and weakens Fire-type moves by 50%.
Accuracy	100%
PP	5 (max. 8)

Rain Dance is a unique move that summons rainfall for the next five turns or until a Pokémon uses another field move like Sunny Day or Sandstorm.

During the rainstorm, Water-type moves have their power doubled. On the flip side, Fire-type moves are weakened by 50%.

A few other moves outside of the Fire-type also get their effectiveness halved by rainfall. These are:

SolarBeam (Grass-type)
Synthesis (Grass-type)
Morning Sun (Normal-type)
Moonlight (Normal-type)

Rain Dance makes fights against Fire-type trainers almost too easy.

Tip: Make sure you have this in your movelist when facing Cinnabar Island’s Blaine and his Fire-type team.

Here are some Water-type Pokémon that desperately need Rain Dance in their movelist:

Pokémon	Type	Location
Slowbro	Water/Psychic	Surf in Slowpoke Well.
Slowking	Water/Psychic	Evolve Slowpoke by trading while holding the King’s Rock.
Golduck	Water	Surf at Route 35, Ilex Forest, Mt. Silver.
Cloyster	Water/Ice	Evolve Shellder.
