Mathematical Formulas & Engine Mechanics

Coverage Score = Count of types hit super-effectively (2x or 4x) by your selected 4 offensive moves without being resisted.

Our calculations strictly follow the official Generation IX game logic implemented by Game Freak in Pokémon Scarlet and Violet. All numbers use integer floor functions at every step rather than standard floating-point rounding, ensuring that min-max damage ranges, stat benchmarks, and multiplier thresholds match in-game tournament hardware precisely.

Worked Battle Examples with Real Numbers

Standard Physical Wallbreaker Build

Inputs: Earthquake, Icicle Crash, Ice Shard, Knock Off

Result: Super effective coverage against 9 types; neutral against 8 types; resisted only by niche dual-types like Bronzong.

Focus Sash Lead Build

Inputs: Stealth Rock, Earthquake, Icicle Spear, Endeavor

Result: Guarantees hazard placement and utilizes Focus Sash + Endeavor + Ice Shard for guaranteed KOs.

Frequently Asked Questions (Moveset & Build Planner)

What is the best item for competitive Mamoswine?

Life Orb provides immediate wallbreaking power across all moves with minimal drawback. Choice Band is preferred for overwhelming raw power, while Focus Sash guarantees survival against faster offensive leads.

Why choose Icicle Crash over Icicle Spear?

Icicle Crash delivers consistent 85 base power with a 30% flinch chance. Icicle Spear is preferred when breaking through Substitute, Focus Sash, or Dragonite's Multiscale.

Can Mamoswine learn Knock Off in Gen 9?

Yes, via TM in the Teal Mask DLC expansion.

Is Ice Shard mandatory on Mamoswine?

On most competitive sets, yes. With 80 base Speed, Mamoswine needs Ice Shard to pick off weakened threats and faster Dragon/Flying types before taking a hit.
