Master the Poison Tera Swampert Raid: Event Dates, Counters, Rewards & Advanced Strategy Guide
Swampert Raid Event Schedule & Capture Rules
Pokemon Scarlet & Violet trainers face a new challenge with Swampert the Unrivalled, a formidable 7-star Tera Raid boss boasting a strategic Poison Tera-type twist.
The Paldea region continues to offer end-game content through these high-difficulty Tera Raids, designed to push trainers’ team-building and tactical skills to their limits.
Originating from the Hoenn region’s Pokemon Ruby & Sapphire, Swampert returns with its classic Water/Ground typing, soon to be complemented by its Mega Evolution’s revival in the upcoming Pokemon Legends Z-A.
This guide provides essential strategies, optimal counter selections, and key details to conquer this powerful raid boss and claim your rewards.
The 7-star Swampert Tera Raid event runs across two distinct periods: first from May 31, 2024, at 00:00 UTC to June 2, 2024, at 23:59 UTC, followed by a second window from June 7, 2024, at 00:00 UTC to June −9, 2024, at 23:59 UTC.
A crucial limitation exists: Swampert the Unrivalled can be captured only once per save file. Subsequent victories after capture will not yield another Swampert, only standard Tera Raid item rewards like Tera Shards and crafting materials.
Swampert’s Battle Profile: Moves, Tera-Type & Key Threats
Swampert presents a complex challenge with its innate Water/Ground dual-typing supported by robust defensive and offensive stats. The defining feature of this encounter is its Poison Tera-type, which significantly alters type effectiveness and demands specific counter strategies.
Its confirmed move pool includes: Earthquake, Yawn, Muddy Water, and Sludge Wave. Trainers must prepare for this specific arsenal.
While Swampert can utilize both physical and special attacks, its physical move Earthquake represents the most immediate threat. Complete immunity via the Levitate ability or Flying-type is strongly recommended, as resistance alone may not suffice given the raid’s inflated damage output.
The status move Yawn poses a major strategic hurdle. Pokemon immune to sleep, such as those with the Insomnia or Vital Spirit abilities, can negate this threat entirely. Alternatively, holding a Chesto Berry provides a one-time safeguard, though it consumes your held item slot.

Beyond Earthquake, trainers must account for STAB (Same-Type Attack Bonus) boosted Water-type attacks and the Poison-type Sludge Wave. Steel-types, while resistant to Poison, carry a fatal weakness to Ground-type moves, making them generally unsuitable for this raid.
The optimal counter strategy centers on resilient Water-type Pokemon that can exploit Swampert’s Poison Tera-type with super-effective Psychic attacks. The ideal candidate possesses either Levitate, a Flying typing, or another Ground immunity, coupled with access to powerful Psychic-type moves or a Psychic Tera-type for a decisive offensive.
Top-Tier Counter Pokemon & Detailed Builds
Selecting the right Pokemon is half the battle. Here are proven, optimized builds designed specifically to topple Swampert the Unrivalled.
Slowbro has cemented its role as a Tera Raid staple due to its exceptional physical bulk and potent setup capability. Its strategy revolves around Calm Mind and Stored Power. Each Calm Mind boost increases both Special Attack and Special Defense, while simultaneously powering up Stored Power, which gains 20 base power for every stat boost on the user.
Adopting a Psychic Tera-type enhances Stored Power’s damage and provides resistance to Sludge Wave. Incorporating Iron Defense bolsters physical defense against Earthquake and further amplifies Stored Power. Chilling Water serves a dual purpose: it’s a safe Water-type move that also lowers Swampert’s Attack stat, increasing your team’s survivability.
Vaporeon offers a different approach with its unique ability, Water Absorb. This not only renders Swampert’s Water-type moves harmless but actually heals Vaporeon, providing crucial sustainability. Its build also focuses on the Calm Mind + Stored Power combo, supported by Psychic Tera.
Since Swampert often opens with Muddy Water, Vaporeon gets a free turn to set up Acid Armor, drastically increasing its physical defense. Holding a Shell Bell complements this by healing a portion of the damage dealt with each attack. For players seeking a faster clear, a Metronome held item can accelerate damage output when spamming Stored Power.
Galarian Articuno is an elite choice if available. Its Psychic/Flying typing grants complete immunity to Earthquake, removing the raid’s biggest threat. It utilizes Agility and Calm Mind to boost its Speed and Special Attack, powering up Stored Power for a devastating finish. The move Reflect can be invaluable for supporting less-durable teammates, reducing the physical damage taken by the entire party.
Latios operates on a similar principle, using its Levitate ability to avoid Earthquake. Beyond the standard Stored Power strategy, it has access to Luster Purge, which has a 50% chance to lower the target’s Special Defense. This debuff can significantly accelerate the raid for you and any special-attacking allies.
Mewtwo remains a powerhouse option for veterans who captured it from a previous event. With its monstrous Special Attack, even a few Calm Mind boosts enable it to unleash catastrophic damage with Stored Power. Its natural bulk, especially when invested in HP and Defense, allows it to withstand several hits while setting up.
Common Strategic Pitfalls & Advanced Optimization
Practical Tip: Don’t underestimate the raid timer. While setting up multiple boosts with Calm Mind is powerful, over-investing turns can cause a timeout loss. Find the balance between sufficient power and speed. Three Calm Mind boosts are often enough to secure a knockout with Stored Power.
Common Mistake: Bringing Pokemon weak to Ground or Water. Avoid Steel, Rock, Fire, and Ground-types entirely. Even resisted hits from a 7-star raid boss can be fatal. The priority is survivability, not just super-effective damage.
Optimization for Advanced Players: Coordinate with online teammates. A team with one dedicated supporter (using moves like Reflect, Light Screen, or Heal Pulse) and three setup sweepers can clear the raid much faster and more reliably than four uncoordinated attackers. Consider using Pokemon with the Ability Misty Surge (like Tapu Fini) to set Psychic Terrain, which boosts Psychic-type moves and protects your team from Yawn.
Raid Rewards & Shiny Information
Victorious trainers who defeat Swampert the Unrivalled earn the opportunity to capture it once per save file. Remember, subsequent wins only grant standard raid loot.
The reward pool for defeating this 7-star boss is generous and includes high-value items such as: Ability Patches (for unlocking Hidden Abilities), various Herba Mystica (for shiny hunting and sandwich recipes), Exp. Candy L/XL, Tera Shards (particularly Poison-type), and valuable sellable items like Nuggets and Pearls.
A key disappointment for collectors: Swampert with the Mightiest Mark cannot be encountered as a Shiny in the raid. This is consistent with all 7-star event raids. However, the captured Swampert is breedable. By breeding it with a Ditto, you can obtain Mudkip eggs, which have the standard chance of hatching into a Shiny Mudkip, following the Masuda Method or other shiny hunting techniques.
This concludes your comprehensive guide to conquering the 7-star Swampert Tera Raid. With the right preparation and Pokemon, you can claim this powerful Water/Ground-type for your collection.
If you’re returning to Paldea for this challenge, consider exploring other guides to round out your team, such as those covering Legendary Pokemon in The Indigo Disk DLC, which may include useful allies like Latios.
