As a Pokémon expert, I'm here to guide you through the process of evolving Yamask. In the Pokémon games, Yamask evolves into Runerigus through a specific method that was introduced in Generation 8. Here's how you do it:


1. Obtain a Yamask: First, you need to have a Yamask in your party.

2. Trade Yamask: You must trade Yamask while it is holding a specific item, the Reaper Cloth. This item is held by default when you first obtain Yamask.

3. Evolution Trigger: The evolution will occur as soon as the trade is completed. The person you are trading with doesn't need to know about the evolution process; the trade itself is enough to trigger the evolution.

Remember, the Reaper Cloth is crucial for the evolution, so ensure Yamask is holding it before initiating the trade.
