Diamond & Pearl Castform Locations
Castform is a rare Trophy Garden catch around level 16, available only once the National Dex opens. That single garden is its whole range, so the weather Pokemon never turns up on a route.
Wild Castform may be holding when caught:
Mystic Water (always) An item to be held by a Pokemon. It is a teardrop-shaped gem that ups the power of Water-type moves.1 location to catch Castform

How to Get Shiny Castform in Diamond & Pearl
Castform drifts through the Trophy Garden, where a PokeRadar chain in that grass brings its shiny in sight. Compare Shiny Castform odds across every game
Shiny Castform Evolution

3 MethodsThe best route is PokeRadar Chain at full boosts, about 1 in 200 on each try. Tune it below.
PokeRadar Chain: Chain shaking-grass patches without breaking the combo. The rate peaks at a chain of 40.
Masuda Method: Breed with a parent from a different-language game. Works on any breedable line.
Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.
How many you have done, or plan to do.
| Chance | Encounters | Time |
|---|---|---|
| 10%lucky few | 22-- | -- |
| 25%one in four | 58-- | -- |
| 50%coin flip | 139-- | -- |
| 90%very likely | 460-- | -- |
Time assumes -- at your pace and does not change your shiny odds.
How is this calculated?
Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.
chance after N tries = 1 − (1 − p)^N, where p = 1 / odds per try
Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.
The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.
These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.
Curious how fast a hunt could go? Work out your Diamond & Pearl shiny odds for Castform.
Castform Weakness
Castform's Normal typing leaves it vulnerable to Fighting. It shrugs off Ghost-type attacks completely. Only 1 weakness makes it relatively easy to build around defensively.
| Damage | Types |
|---|---|
| 2x (Weak) | Fighting |
| 0x (Immune) | Ghost |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

The natural movepool does the job, but Amnesia and Disable from the egg pool give Castform something extra. Pair those with Double-Edge and Body Slam for STAB and coverage across 8 types for reach, and the kit fills out nicely.
