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.
These Pokémon arose from the spirits of people interred in graves. Each retains memories of its former life.
Each of them carries a mask that used to be its face when it was human. Sometimes they look at it and cry.
Yamask Weakness
ExcellentType-wise, Yamask takes extra damage from Ghost and Dark. Normal and Fighting moves do nothing thanks to a full immunity.
One evolution ahead. Yamask grows into Cofagrigus through a straightforward two-stage chain. No compatible partners for breeding via two egg groups. Eggs are average hatch time. Evolving adds up to 180 stat points total.
How to Evolve
Breed Yamask easily from the Indeterminate and Mineral egg groups. Pass egg moves like Ally Switch, Disable, Endure and 7 more to offspring.

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.
