Evolving Yamask into Cofagrigus: A Comprehensive Guide

The world of Pokémon is always fascinating, with new generations of games introducing new features and gameplay mechanics. The recent games, Pokémon Sword and Shield, have given us the opportunity to catch and evolve various Pokémon to enhance their strengths and attributes. Among the many interesting Pokémon available in these games, Yamask and Cofagrigus have a unique story of evolution, and we’ll explore this topic in detail.

Understanding Yamask and its Evolution

Yamask is a ghost-type Pokémon introduced in Pokémon Black and White, while Cofagrigus is an evolved form of Yamask that has been seen in several subsequent games, including Sword and Shield. Cofagrigus is an evolved form that offers unique attributes and combat advantages compared to its non-evolved state.

To understand the evolution process better, we need to learn how Yamask evolves. As a non-evolved form, Yamask must reach level 34 or above, then take on the "sacrificing body" ability ( This means Yamask has to receive 49 damage ). After accomplishing these steps, trainers can access the Dusty Bowl area in the Wild Area to continue the evolution process. There, a player’s Yamask evolves into a Runerigus. The evolution, unfortunately, only occurs this way in the Wild Area and doesn’t work at Pokémon Centers, PC areas, or even in trades with other trainers.

Now that we understand the background information on Yamask’s evolution, we can shift our attention to the following important question: how to evolve Yamask into Cofagrigus.

Evolving Yamask into Cofagrigus

Cofagrigus evolves from Yamask’s evolved form, Runerigus, by further infusing it with ancient energies. According to game developers, infusing these energies requires performing specific steps within the in-game mechanics.

Here is the exact procedure to infuse Yamask into Cofagrigus:

  • Trade a Runerigus (which is now Yamask’s evolved state) twice
    • Perform the second trade, where the target accepts your trade offer of Runerigus without sending it to the server first (more on server requests in a moment). Ensure both you and your opponent (your friend/trading partner) have updated your copy of the games. Ensure your friend confirms acceptance. Now, check both sides. If, indeed, it’s possible for another friend to also acquire Yamask, try. (As you send out to battle, see in Battle Log, and have friends send an inquiry from an account.

For additional help, kindly watch for server- side inquiries. On each transfer of the evolving creature’s position, which are more often than initially suspected.
It is advisable that this evolution process isn’t feasible from trades with opponents but has not been specifically discredited, and an option.
Cofagrigus’ evolution occurs immediately in both cases for trainers using Sword and Shield versions and the most likely approach, which happens only at home ( Cofagrigus evolved the moment their evolution conditions are met *** ).

By following the simple yet important steps ( a detailed guide ) to infuse energies in the form of multiple trades with the Runerigus form, any trainers using the Sword or Shield version can successfully achieve Cofagrigus’s evolution.
