Stats & Training
The stat line revolves around Attack. Percentage recovery gets extra mileage here. HP backs it up, though Sp. Def doesn't pull its weight. Worth 3 Attack EVs on a slow 1.25M XP grind to max out.
This species reached its zenith during the period known as the ice age. I suspect that Hisui’s frigid climate is in harmony with Mamoswine’s constitution, thus awakening hidden potential.
Mamoswine Weakness
Fire, Water, Grass, Fighting, and Steel moves hit Mamoswine for super-effective damage. The upside? Electric-type moves can't touch it at all. Thick Fat reduces Fire/Ice damage, further improving the defensive spread.

Ultra Sun & Ultra Moon Mamoswine Best Moveset

How to Get Mamoswine in Ultra Sun & Ultra Moon
Can't catch Mamoswine directly. Start with Swinub at moderate rates from the locations below, then evolve through a special method. The 3-stage chain from Swinub to Mamoswine is where the leveling time goes.
Mamoswine Guide
In Ultra Sun & Ultra Moon, Mamoswine looks average on paper at 530 BST. But Thick Fat is why it sees play. Build around that and it pulls its weight. A-Tier wallbreaker on our tier list. Earthquake with Life Orb is the standard set.
Mamoswine gets Thick Fat, Oblivious, and Snow Cloak. But Thick Fat is the one that matters. It's the centerpiece of every viable set. Build around that.
Mamoswine is a physical attacker with base 130 Attack. Enough bulk to take a hit or two, too. Speed tells the real story. Base 80 Speed is workable. Faster than some, slower than many. Fits the wallbreaker role.
For Ultra Sun & Ultra Moon, Mamoswine has answers, but so do you. Status moves (Toxic, Will-O-Wisp) wear it down. Setup sweepers can use it as a boost opportunity. Special attackers bypass its physical bulk.
Game Availability
Debuting in Diamond & Pearl, Mamoswine appears in 13 games across 7 generations. A reliable presence in a solid number of games, typically found through wild encounters.
