How to Get Shiny Gastly in Ultra Sun & Ultra Moon
Gastly drifts through Hau'oli Cemetery; a long SOS chain there lifts the shiny rate to 1 in 274. Compare Shiny Gastly odds across every game
Ultra Sun & Ultra Moon Shiny Gastly Calculator
3 MethodsThe best route is SOS Chaining at full boosts, about 1 in 274 on each try. Tune it below.
SOS Chaining: Leave one ally fainted and force endless calls. Bonus rolls step up at 11, 21, and 31 calls.
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 |
|---|---|
| 10%lucky few | 29 |
| 25%one in four | 79 |
| 50%coin flip | 190 |
| 90%very likely | 630 |
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.

Gastly Weakness
Gastly is weak to Ground, Psychic, Ghost, and Dark. On the flip side, it's immune to Normal and Fighting-type moves entirely. The Ghost/Poison typing picks up 4 resistances to work with. Levitate grants an additional Ground immunity, reshaping the matchup chart. Gastly leans toward special offense (base 100 Sp.Atk) instead of trying to wall anything.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic, Ghost, Dark |
| 0.5x (Resist) | Grass, Fairy |
| 0.25x (Resist) | Poison, Bug |
| 0x (Immune) | Normal, Fighting |
