Regirock is a Rock-type Legendary Pokémon originally discovered in the Hoenn region. Regirock’s body is comprised entirely of rocks with no sign of a brain or heart; it is a mystery even to modern scientists. Learn which Pokémon will be most effective in Raid Battles against Regirock, how to catch Regirock after winning a Raid Battle, and how best to use the Rock Peak Pokémon after you’ve caught it.

Which Pokémon to Use in a Regirock Raid in Pokémon GO

As a Rock-type Pokémon, Regirock is vulnerable to Water-, Grass-, Fighting-, Ground-, and Steel-type attacks. When selecting Pokémon for your Regirock Raid Battle lineup, it helps to choose Pokémon that have a Fast Attack and a Charged Attack of one of these types if you want to deal as much damage as possible. A Pokémon that shares a type with these attacks will benefit from a same-type attack bonus, which will allow these attacks to deal an additional 20% damage.

If you have multiple Pokémon that know Water-, Grass, Fighting-, Ground-, or Steel-type attacks, choose the Pokémon with the highest CP and best overall stats. Remember that speed of victory affects how many Premier Balls you will receive at the conclusion of a successful Raid Battle, so bring your strongest Pokémon and defeat Regirock as quickly as possible.

Make the Most of Premier Balls and Berries

After a successful Regirock raid, you’ll have a limited number of Premier Balls you can use to catch Regirock, so make each one count. You can earn extra Premier Balls by battling with friends and defeating Regirock more quickly.

In an encounter with Regirock, your chance of catching it is greatest when the target ring is small enough for you to score Excellent Throws. Throwing Curveballs can improve your chances even more. But work within your abilities—if you don’t think you can reliably make Excellent Curveball Throws, aim for Nice Throws or Great Throws rather than risk missing the target ring completely.

Regirock isn’t going to make it easy on you by sitting still while you’re trying to catch it. Don’t waste your Premier Balls by throwing while it’s moving around. Watch Regirock to get a feel for its cycle of movement and the pauses in between the cycles. During one of these pauses, wait for the target ring to reappear, and then throw as it starts to grow smaller to increase your odds of making a Great Throw or an Excellent Throw.

Berries can help you catch Regirock. A Razz Berry will make Regirock easier to catch, and a Golden Razz Berry will make it much easier to catch. If you find yourself failing to land any throws, a Nanab Berry will calm Regirock, making its movements less erratic and allowing you to make precise throws more easily. If you need extra Regirock Candy, using a Silver Pinap Berry will make Regirock easier to catch and grant you extra Candy when you catch it.

Buddy Pokémon with a Buddy Level of Great Buddy or higher have the Catch Assist Perk. If a Pokémon—even a Legendary Pokémon—deflects a Poké Ball, your buddy might bounce it back for a second catch opportunity!

Like all Legendary Pokémon, Regirock is tricky to catch, so don’t be discouraged if it escapes. Get a second wind by stocking up on useful items—like Max Potions, Max Revives, and Golden Razz Berries—and try again.

What to Do with Regirock Once You’ve Caught It

As a Rock-type Pokémon, Regirock is resistant to Normal-, Fire-, Poison-, and Flying-type attacks.

While Regirock is not considered a top-tier Pokémon in the GO Battle League, it can be a rock-solid addition to your lineup. Given the prominence of Flying-type Pokémon in Ultra League, Regirock’s Rock-type attacks could certainly come in handy. Its wide range of Fast Attack and Charged Attack types gives it some versatility—when faced with one of the many Steel-type Pokémon popular in the Ultra League, Regirock’s Fighting- or Ground-type Charged Attack can provide an effective counter.

Choosing the best attacks to complement your lineup and overall strategy is an essential part of battling in the GO Battle League. While Lock-On doesn’t deal a lot of damage, this Fast Attack powers up Regirock’s Charged Attacks quickly. And you’re going to need it—while Regirock’s Charged Attacks deal substantial damage, they require a lot of energy to use. For this reason, Regirock might not be the best lead Pokémon in your lineup. Save Regirock until an opponent’s Protect Shields are gone before unleashing the wrath of this mountainous Pokémon.

You have many solid options for Regirock’s Charged Attack. Stone Edge benefits from a same-type attack bonus, allowing you to rock your opponent with extra damage. A second Charged Attack will make your Pokémon more effective in battle, and Focus Blast may be the ticket to keeping your opponents on their toes. This Fighting-type Charged Attack is a sound counter to Steel-type Pokémon, one of Regirock’s weaknesses.

If you're aiming to bring Regirock to the GO Battle League, you should power it up as much as possible for the league you want to compete in and teach it a second Charged Attack. Raising Regirock’s CP to its maximum requires a lot of Regirock Candy and Stardust, so try to catch as many Regirock as possible to help you get there faster—and don’t forget the Pinap Berries!
