Catch a Yamask

To start you want to catch yourself a Yamask (if you have one already ignore this section). Yamask can be found along Route 6 between Hammerlock and Stow-on-Side. Yamask is rather common along this route so catching one shouldn’t be an issue. The thing to keep in mind here is you want to catch a Yamask with Max Health above 50 (this comes into play later). Once you’ve met the required criteria continue to the next step.

Have Yamask Take 49+ Health Damage

Now that you have a Yamask, equip it and fight other Pokemon. The goal here is to have Yamask take at least 49 health damage from an enemy Pokemon. To do this I recommend fighting Pokemon at or below its level. Keep in mind you do not want Yamask to faint. You just need it to lose 49 health. Once this happens it’s onto the next step.
