Galarian Yamask hides one of the strangest evolution tricks in Pokémon Legends: Z-A – a method that ties mystery, location, and endurance into a single challenge few trainers spot on their first try.
In Pokémon Legends: Z-A, Galarian Yamask needs to meet certain conditions to evolve into Runerigus. It just needs to take some damage before you stand under one of two specific bridges in Lumiose City, so the hardest part of evolving it may be catching it in the first place: Galarian Yamask can be caught in Hyperspace Lumiose, and when it shows up is at the luck of the draw.
Galarian Yamask was added to Pokémon Legends: Z-A in the Hyperspace Pokédex as part of the Mega Dimension DLC. If you don’t have the DLC, a willing trainer can always trade you the Pokémon if you want to use it in the base game.
Where is the Coulant Waterway Bridge in Lumiose City located
The Coulant Waterway Bridge spans the Coulant Waterway canal in Lumiose City’s Vert District.
Location Details
It lies east of Vert Sector 3 and west of Vert Sector 6, with the key spot for evolutions directly underneath the bridge between Wild Zones 11 and 17. Check your in-game map for the eastern side of Lumiose City, where two bridges cross the waterway southeast of Wild Zone 2 or near Wild Zone 17.
Access Tips
Head to the Vert District via South Boulevard, then locate the canal fork from Saison Canal running toward Vert Street. Stand under the bridge with Galarian Yamask in your party (after it takes 49+ damage) and check the menu to evolve it. Nearby landmarks include construction platforms and arguing NPCs in Wild Zone 11.
