Singles Moveset for Regirock

Stealth Rock Lead Moveset & Best Build

What sets Regirock apart as a Stealth Rock user is its resistance to Fire. Other popular Stealth Rock users like Skarmory or Ferrothorn share a weakness to Fire. These Pokemon typically do not like taking Fire-type hits, whereas Regirock can take them quite nicely.

About Regirock's Moves

Stone Edge is Regirock's most powerful STAB move. Because of its low accuracy, Rock Slide is a good substitute for it. Regirock's massive Defense Stat makes it an effective user of Body Press.

Stealth Rock is important for this Stealth Rock set, as Regirock can comfortably take a physical attack and set up its entry hazards. Spreading paralysis with Thunder Wave is also good after successfully setting up Stealth Rock.

About Regirock's EV Spread

Fully investing in HP and Special Defense makes Regirock a powerful counter to most Fire-type Pokemon. Its enormous Defense stat needs no further improvement, which is why we invest into its Special bulk.

About Regirock's Ability

Clear Body protects Regirock from status reduction, most importantly from Attack drops from Intimidate.

About Regirock's Held Item

Leftovers provides passive recovery for Regirock.

Other Viable Moves

Doubles Moveset for Regirock

Weakness Policy Moveset & Best Build

Regirock's enormous Defense, decent Attack and useful Ability make it a very formidable attacker and abuser of Weakness Policy. Protecting it from Special Attackers and positioning it to take KO's against Rock-weak Pokemon are ways to pilot Regirock to success.

About Regirock's Moves

Rock Slide is a reliable STAB spread move for Regirock. Stomping Tantrum is used over Earthquake so that Regirock has options against opponents that could possibly run Wide Guard. Drain Punch provides Regirock with much needed recovery.

Curse is good for improving Regirock's effectivity under Trick Room. Curse can be swapped out for Protect, which is always a good choice for Double Battles.

About Regirock's EV Spread

Maximizing Regirock's HP and Attack stats ensure that it can hit as hard as possible while being as physically bulky as possible. Putting all defensive EVs into HP works well with its naturally high Defense stat.

0 Speed IVs allow Regirock to be as slow as possible under the conditions of Trick Room.

About Regirock's Ability

Clear Body protects Regirock from status reduction, most importantly from Attack drops from Intimidate.

About Regirock's Held Item

Weakness Policy works hand-in-hand with Regirock's high Defense stat. It can comfortably take most physical hits, and be able to hit back for big damage.

Other Viable Moves

How to Use Regirock Effectively

Regirock works best exchanging blows against Physical Attackers on account of its huge Defense stat. It also works best attacking into Physically weak Pokemon. Positioning Regirock so that it can take decisive KO's are important to this Pokemon's success.

How to Build a Team with Regirock

Regirock thrives in Trick Room, and a teammate that can set it up is greatly appreciated by it. Dual Screens is also great for Regirock because of the much appreciated boost to its defenses, most especially its Special Defense. Regirock also enjoys teammates that can take care of Grass-types that threaten it.

Weakness Policy Attacker

Regirock's gigantic Defense stat will let it survive a super-effective Physical attack. Having it hold Weakness Policy will cause opponents to think twice before attacking into it.

Example Regirock Team

Trick Room Setter	Offensive Tank	Support
Porygon2	Regirock	Grimmsnarl

Regirock's horrendous Speed makes it a great Trick Room Attacker, with Porygon2 setting Trick Room up for it. Grimmsnarl provides Screens support for Regirock, which can allow it to survive a super-effective hit and activate its Weakness Policy.

Counters for Regirock

Weakness

Beat Regirock with Super-effective Special Attacks and Status Conditions

Regirock has a decent Special Defense Stat, but its weakness to common types make it very vulnerable on the battlefield. A super-effective Special Attack will surely deal massive damage to Regirock, if not just knock it out cleanly.

Regirock also has a bad time against status conditions. It does not appreciate Sleep and Burns. Dynamaxing Regirock can give it trouble against redirection because Dynamax only allows for single targets.
