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.
A clay slab with cursed engravings took possession of a Yamask. The slab is said to be absorbing the Yamask’s dark power.
It’s said that this Pokémon was formed when an ancient clay tablet was drawn to a vengeful spirit.
Type-wise, Yamask takes extra damage from Ghost and Dark. Normal and Fighting moves do nothing thanks to a full immunity.

| 2x (Weak) | Ghost, Dark |
| 0.5x (Resist) | Poison, Bug |

One evolution ahead. Yamask grows into Cofagrigus through a straightforward two-stage chain. Plenty of partners for breeding via two egg groups. Eggs are average hatch time. Evolving adds up to 180 stat points total. View every chain in the Evolution Chart.
How to Evolve
The build centers on Toxic Spikes and survivability. Eviolite means a bulk boost that only works before full evolution, and spread EVs give Yamask the bulk to set up repeatedly. Mummy adds another layer of staying power.

Moves
TMs carry this one. Yamask learns Phantom Force and Shadow Ball naturally for STAB, but the offensive range comes almost entirely from technical machines. Psychic and Bug and beyond give it real matchup play.
Level-Up Moves
TM Moves
Egg Moves
Tutor Moves
Leveling does the heavy lifting. Yamask picks up Energy Ball and Psychic along the way, building toward a complete offensive set. TMs add Dark and Grass coverage and more, but the foundation's already strong by then.
The egg pool carries weight here. Ally Switch and Crafty Shield 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.
