How to Evolve Swinub

Evolving Swinub is a two-step process that shifts from standard leveling to a move-based requirement. The first stage is straightforward: Swinub evolves into Piloswine automatically upon reaching Level 33. No items or specific locations are required for this initial phase.

The transition from Piloswine to Mamoswine requires specific mechanical manipulation. Piloswine must level up while having the Rock-type move Ancient Power in its active moveset. If Piloswine levels up without this move, the evolution will not trigger.

Because Piloswine does not naturally learn Ancient Power through standard leveling at higher levels, you must actively intervene. If you cancel the evolution animation by pressing B, you simply need to level up Piloswine again while Ancient Power remains in its moveset to retry.

The method for teaching Ancient Power to Piloswine depends entirely on which generation you are playing. Mamoswine was introduced in Generation 4, meaning this evolution method does not exist in Pokémon Gold, Silver, Crystal, Ruby, Sapphire, or Emerald.

In Generations 4 through 7 (Diamond/Pearl up to Sun/Moon), you must visit the Move Reminder NPC. This requires spending a Heart Scale, an item often found by using Thief on wild Luvdisc or mining in the Underground. The Move Reminder will teach Ancient Power from Piloswine's base movepool.

Modern generations streamline this process significantly. In Generation 8 (Sword/Shield and Brilliant Diamond/Shining Pearl), the Move Reminder is located inside every Pokémon Center and charges no fee. In Generation 9 (Scarlet/Violet), you bypass NPCs entirely. Simply open Piloswine's summary screen, select the moves menu, and choose 'Remember Moves' to equip Ancient Power for free before leveling up.

Competitive Rating: 8.5/10. Mamoswine operates as a top-tier Physical Wallbreaker and dedicated revenge killer in competitive singles formats. Its primary asset is a massive Base 130 Attack stat paired with one of the best offensive typings in the game: Ice and Ground.

This dual STAB (Same Type Attack Bonus) combination provides unresisted coverage against a massive portion of the metagame. Mamoswine naturally threatens dominant Dragon, Flying, Ground, and Steel types. Its Base 80 Speed is mediocre, but Mamoswine bypasses this flaw entirely by utilizing Ice Shard, a priority move that allows it to strike faster threats like Garchomp, Landorus-Therian, and Salamence before they can act.

For optimal performance, Mamoswine requires its Hidden Ability, Thick Fat. This ability halves the damage taken from Fire and Ice-type attacks, effectively removing its Fire weakness and granting it a crucial resistance to Ice. Snow Cloak and Oblivious offer minimal competitive value by comparison.

Mamoswine fits best on Hyper Offense and Bulky Offense teams that need an immediate answer to fast setup sweepers or a reliable Stealth Rock setter. It is a poor fit for Stall or highly defensive teams due to its lack of reliable recovery and average defensive stats (110 HP, 80 Defense, 60 Special Defense).

• Pros: Elite offensive typing, access to STAB priority (Ice Shard), immunity to Electric-type moves and Sandstorm damage, heavily pressures entry hazard removers.
• Cons: Weak to common attacking types (Fighting, Water, Grass, Steel), slow without priority, easily worn down by entry hazards and Life Orb recoil.

Pair Mamoswine with slow pivots like Corviknight or Rotom-Wash. These teammates can absorb the Steel and Water attacks aimed at Mamoswine and use U-turn or Volt Switch to bring it safely onto the field, maximizing its wallbreaking opportunities.

To maximize Mamoswine's offensive output after evolution, equip it with a Life Orb or Choice Band. A Focus Sash is an alternative if you are using Mamoswine strictly as a suicide lead to guarantee Stealth Rock placement.

The mandatory offensive core consists of Earthquake and Icicle Crash for heavy STAB damage, alongside Ice Shard for priority revenge killing. The fourth slot is flexible. Knock Off provides excellent utility by removing items from switch-ins like Heavy-Duty Boots or Leftovers. Alternatively, Stealth Rock exploits the switches Mamoswine forces, allowing it to set hazards while the opponent retreats.

Invest 252 EVs in Attack and 252 EVs in Speed, utilizing either a Jolly or Adamant nature. Jolly allows Mamoswine to outspeed neutral-natured base 80s and slower variants of defensive Pokémon, while Adamant maximizes the raw damage output of Ice Shard.
