1 MethodThe only route here is Soft Reset, about 1 in 8,192 on each try.
Soft Reset: Save in front of a static, gift, or legendary encounter, then reset until it sparkles.
How many you have done, or plan to do.
| Chance | Encounters | Time |
|---|---|---|
| 10%lucky few | 864-- | -- |
| 25%one in four | 2,357-- | -- |
| 50%coin flip | 5,678-- | -- |
| 90%very likely | 18,862-- | -- |
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.
For time estimates and charm math, open the Ruby & Sapphire shiny odds calculator with Groudon already selected.
Groudon Weakness
Groudon's Ground typing leaves it vulnerable to Water, Grass, and Ice. It shrugs off Electric-type attacks completely. Groudon's physical bulk (base 140 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Water, Grass, Ice |
| 0.5x (Resist) | Poison, Rock |
| 0x (Immune) | Electric |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
