How To Evolve Yamask Legends ZA And Meet The Evolution Requirements

Evolving Yamask in Pokémon Legends Z-A requires players to understand the distinct mechanics tied to its regional forms. While standard Unovan Yamask follows a straightforward progression path, its Galarian counterpart demands a precise set of environmental and combat conditions. Navigating these requirements effectively ensures you can add both Cofagrigus and Runerigus to your team without unnecessary frustration.
Standard Yamask Evolution to Cofagrigus
For trainers raising the traditional Ghost-type Yamask, reaching its final form is a simple matter of combat experience. Yamask automatically unlocks the ability to evolve into Cofagrigus once it reaches level 34. Players simply need to keep Yamask in their active party during expeditions or utilize EXP candy to reach this milestone quickly.
Once the level threshold is achieved, open your party menu to manually trigger the evolution. Unlike other complex evolution methods in Lumiose City, standard Yamask does not require specific battle locations or held items. This straightforward leveling process makes Cofagrigus an accessible defender for your mid-game roster.
Unlocking Runerigus via Galarian Yamask
Evolving Galarian Yamask into Runerigus introduces a far more mysterious set of prerequisites. This Ground and Ghost-type variant must endure a specific amount of battle damage before the transformation becomes available. Specifically, your Galarian Yamask needs to lose at least 49 hit points from direct enemy attacks without fainting.
Indirect damage sources such as weather effects or status conditions like poison do not count toward this total. Furthermore, healing Yamask before reaching the required location will reset the progress, forcing you to restart the process. Maintaining a damaged state while traveling requires careful navigation through surrounding wild areas.
Reaching the Specific Bridge Location
After successfully taking 49 or more points of direct damage, you must travel to a designated landmark on the map. Bring your damaged Galarian Yamask to the stone bridge located near Coulant Waterway, positioned northwest of Wild Zone 17. Position your character directly underneath the archways of the bridge rather than on top of it.
Once standing beneath the structure, access your main menu and inspect Galarian Yamask. You will notice the evolution prompt is now active, allowing you to transform it into Runerigus. Standing in the exact zone is crucial, as moving outside the bridge perimeter will make the option unavailable.
Tips for Managing Damage and Staying Alive
To safely complete the health requirement, battle lower-level wild Pokémon that deal predictable damage. Raising Galarian Yamask above level 30 gives it a larger health pool, making it easier to absorb 49 damage safely. Using moves like Endure can also protect your Pokémon from accidentally fainting during heavy hits.
Once the damage threshold is met, flee from combat immediately to prevent further damage. Avoid visiting Pokémon Centers or using recovery items while heading toward Coulant Waterway. Following these precise steps guarantees a smooth evolution into the formidable Runerigus.
