Is Slaking Good in Ruby & Sapphire Playthrough?

670 BST but AbilityTruant forces a skip every other turn. Slaking hits harder than anything else in RS on its active turns. The truant cycle means opponents get free hits every other turn. Norman's ace for a reason. Devastating when it attacks. Vulnerable when it doesn't.

How to Get Slaking in Ruby & Sapphire

Vigoroth becomes Slaking at level 36, the only route to it since none appear in the wild. Catching that one rare Slakoth was the hard part, and this is just the payoff.

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.

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

Curious how fast a hunt could go? Work out your Ruby & Sapphire shiny odds for Slaking.

Slaking Weakness

Fighting moves hit Slaking for super-effective damage. The upside? Ghost-type moves can't touch it at all. Slaking's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokedex Entry

SLAKING spends all day lying down and lolling about. It eats grass growing within its reach. If it eats all the grass it can reach, this POKéMON reluctantly moves to another spot.

Wherever SLAKING live, rings of over a yard in diameter appear in grassy fields. They are made by the POKéMON as it eats all the grass within reach while lying prone on the ground.
