Is Dustox Good in Ruby & Sapphire Playthrough?

Bug/Poison with AbilityShield Dust. Dustox is the defensive Wurmple evolution with better bulk than Beautifly. MoveLight Screen support helps the team through harder fights. Fades by mid-game but the early defensive utility is decent.

How to Get Dustox in Ruby & Sapphire

Cascoon reaches Dustox at level 10, the only path since none appear in grass. It sits on the opposite branch of that random Wurmple split from Beautifly.

Wild Dustox may be holding when caught:

Silver Powder (5% chance) A hold item that raises the power of BUG-type moves.

Catch Wurmple or Cascoon at any of these 4 spots to eventually evolve into Dustox.

2 Methods
Shiny Odds

Both methods here share the same odds, about 1 in 8,192 on each try. Pick whichever fits how you play.

Step 1 · Encounter Method2 in Ruby & Sapphire

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.

120,000
Shiny Odds Per Try1 / 8,192Full Odds

What To Expect
ChanceEncountersTime
10%lucky few864----
25%one in four2,357----
50%coin flip5,678----
90%very likely18,862----
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.

Where these shiny odds come from: Read our full methodology

Pokedex Entry

DUSTOX is instinctively drawn to light. Swarms of this POKéMON are attracted by the bright lights of cities, where they wreak havoc by stripping the leaves off roadside trees for food.

When DUSTOX flaps its wings, a fine dust is scattered all over. This dust is actually a powerful poison that will even make a pro wrestler sick. This POKéMON searches for food using its antennae like radar.

Dustox Ruby & Sapphire Guide

  • Dustox is obtained in Pokemon Ruby & Sapphire by evolving Cascoon under specific conditions.

Game Availability

Debuting in Ruby & Sapphire, Dustox appears in 14 games across 7 generations. A reliable presence in a solid number of games, typically found through wild encounters.
