Yamask sits at the start of its evolution line — not yet at full power, but that changes fast. Most trainers push through to Cofagrigus as fast as possible. Normal and Fighting moves can't touch it, and only 2 types hit it super-effectively. Known as the Spirit Pokemon.

Defense and Sp. Def carry most of Yamask's stat budget. Attack's the obvious dump stat. Common in the wild and yields 1 Defense EV. Follows a medium-fast 1M XP curve.

Best Build

No build content available for this Pokemon in Gen 6.

Try selecting a different game/generation filter, or check back later.

The egg pool carries weight here. Ally Switch and Disable aren't available any other way for Yamask, and they meaningfully change what it threatens. Stack those on top of Shadow Ball and Hex for solid options.

  • Yamask is meant to evolve into Cofagrigus. At 303 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.

  • Yamask's biggest threats include Dusknoir (Ghost) and Weavile (Dark), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about. At base 30 Speed, Yamask won't outrun any of these threats so switching to a resist is usually the safer play.

  • Yamask can evolve into Cofagrigus and Galarian Runerigus depending on the method. Yamask is the base form in a 3-stage evolutionary line.

  • Mummy is the go-to ability for Yamask. It changes attacking Pokémon's abilities to Mummy on contact. It's Yamask's only ability.

  • Base 30 Speed is low. Priority moves or Trick Room are the way to go. On offense, Yamask is a special attacker with base 55 Sp. Atk.

  • Yamask appears in 8 games, including Black & White, Black 2 & White 2, and X & Y.

Since debuting in Black & White, Yamask has appeared in 8 titles over 5 generations. Along the way, it received a Galarian form in Generation 8, keeping it relevant across different competitive metas.
