How to Get Koffing in Ruby & Sapphire
Koffing drifts through the Fiery Path, and the versions disagree on how often: Ruby has it as a common level-15 catch, while Sapphire makes it a rare level-14 find. That smoky cave is its only home.
Wild Koffing may be holding when caught:
Smoke Ball (5% chance) A hold item that can be used to flee from a wild Pokemon.1 location to catch Koffing
Encountered via tall grass encounters

How to Get Shiny Koffing in Ruby & Sapphire

Ruby & Sapphire Shiny Koffing Calculator
2 MethodsBoth methods here share the same odds, about 1 in 8,192 on each try. Pick whichever fits how you play.
Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.
Breeding: Hatch eggs of this line; each egg rolls at the base shiny rate (no Masuda before Gen IV).
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.

Koffing Weakness
Ground and Psychic moves hit Koffing for super-effective damage. 4 resistances help offset the weaknesses. Levitate grants an additional Ground immunity, reshaping the matchup chart. Koffing's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic |
| 0.5x (Resist) | Grass, Fighting, Poison, Bug |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move

Base Stats
If KOFFING becomes agitated, it raises the toxicity of its internal gases and jets them out from all over its body. This POKéMON may also overinflate its round body, then explode.
KOFFING embodies toxic substances. It mixes the toxins with raw garbage to set off a chemical reaction that results in a terribly powerful poison gas. The higher the temperature, the more gas is concocted by this POKéMON.
Koffing Ruby & Sapphire Guide
Yes. Wild Koffing in Ruby & Sapphire can hold Smoke Ball (5%). Use Thief (TM46) or Covet to swipe the held item without affecting your catch chance. Quickest way to farm rare items like Smoke Ball.
