Stats & Training
Defense and Sp. Def carry most of Yamask's stat budget. Sp. Atk's the obvious dump stat. Common in the wild and yields 1 Defense EV. Follows a medium-fast 1M XP curve.
Each Yamask carries a mask representing the face it had when it was still human. Sometimes it gazes at the mask and weeps.

Evolution
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
Breeding
Breed Yamask easily with 63 breeding partners from the Indeterminate and Mineral egg groups.
Yamask Best Moveset
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.

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.
