How to Evolve Corphish

Corphish evolves into Crawdaunt exactly at level 30. This flat level requirement applies across all mainline games, from its debut in Pokémon Ruby and Sapphire to modern titles like Pokémon Scarlet and Violet.

You do not need to use a Water Stone, trade the Pokémon, or wait for a specific time of day. Reaching level 30 triggers the evolution screen immediately after the battle concludes or the EXP Candy is consumed.

In older Generation 3 and Generation 4 games, players typically catch Corphish at levels 20 to 25 using a Good Rod. Grinding five to ten levels requires battling route trainers or wild Pokémon. Modern generations simplify this process entirely.

Using EXP Candies obtained from Tera Raids or Max Raid Battles allows you to bypass traditional grinding. A single EXP Candy L provides 10,000 EXP, which instantly pushes a newly hatched level 1 Corphish close to its evolution threshold.

Crawdaunt relies entirely on its Hidden Ability, Adaptability. This ability increases the Same Type Attack Bonus (STAB) multiplier from the standard 1.5x to a massive 2.0x. Shell Armor and Hyper Cutter offer zero offensive utility and should be actively avoided.

With a base 120 Attack stat and Adaptability, Crawdaunt hits harder than many legendary Pokémon. A Choice Band-boosted Crabhammer can cleanly two-hit KO (2HKO) even physically defensive walls that resist Water-type attacks.

However, Crawdaunt suffers from a crippling base 55 Speed and poor bulk (63 HP / 85 Defense / 55 Special Defense). It cannot switch into attacks safely and will be outsped by almost every offensive threat in the standard metagame.

To maximize Crawdaunt's wallbreaking potential, you must run a specific four-attack moveset or a Swords Dance setup variant. Knock Off and Crabhammer are mandatory STAB moves. Knock Off removes enemy items while dealing boosted damage on the first hit, effectively reaching 130 Base Power before the Adaptability multiplier.

Aqua Jet is the third non-negotiable move. Because Crawdaunt is incredibly slow, Aqua Jet provides STAB-boosted priority to pick off weakened, faster threats. Without Aqua Jet, Crawdaunt becomes dead weight against hyper-offense teams.

• Knock Off: Primary Dark-type STAB, removes Heavy-Duty Boots and Leftovers.
• Crabhammer: Primary Water-type STAB, high critical hit ratio, massive base power.
• Aqua Jet: Mandatory priority to bypass base 55 Speed.
• Swords Dance / Close Combat: Setup for sweeping or coverage against Steel and Dark types.

For the item slot, Life Orb grants a 1.3x damage boost while allowing you to switch moves, making it ideal for Swords Dance sets. Choice Band locks you into one move but provides immediate, devastating power right off the bat.

Crawdaunt is built for players who employ slow pivoting strategies. You need teammates with moves like Teleport, slow U-turn, or Volt Switch to bring Crawdaunt onto the field without taking damage. Defensive pivots like Corviknight or Slowbro pair perfectly with this glass cannon.

This Pokémon excels when the opponent relies heavily on passive defensive walls like Toxapex, Blissey, or Mandibuzz. Crawdaunt functions as a dedicated stallbreaker, easily forcing switches and dismantling defensive backbones with Knock Off.

Conversely, you should not use Crawdaunt if your team lacks speed control or entry hazard removal. Crawdaunt is highly susceptible to Spikes and Stealth Rock, which chip away at its already fragile HP pool. Players running fast-paced hyper-offense teams will find Crawdaunt too slow and reliant on setup.

Avoid leaving Crawdaunt in against faster priority users. Pokémon with Mach Punch or Extreme Speed will easily OHKO it before it can fire off an Aqua Jet.

Optimizing Crawdaunt requires strict attention to Effort Values (EVs) and Natures. A standard spread allocates 252 EVs to Attack and 252 EVs to Speed, with the remaining 4 EVs placed in Defense. Maximizing Speed is necessary to outpace base 50 Speed defensive Pokémon, such as Chansey or Azumarill.

Choosing between an Adamant Nature (+Attack, -Special Attack) and a Jolly Nature (+Speed, -Special Attack) dictates your specific matchups. Adamant guarantees certain OHKOs with Aqua Jet against frail sweepers, while Jolly allows you to outspeed specific defensive threats before they can use Recover or Toxic.

If you are catching Corphish in the wild, you will need an Ability Patch to change its standard ability to Adaptability. Breeding a female Crawdaunt with Adaptability guarantees a 60% chance to pass the Hidden Ability down to the newly hatched Corphish.

Egg moves are also crucial. Aqua Jet is an Egg Move in many generations, requiring you to breed Corphish with a compatible parent, such as Golduck or Floatzel, that already knows the move. In Generation 9, you can simply use the Mirror Herb mechanic to transfer Aqua Jet instantly without breeding.
