by

To Mega Evolve Ampharos in Pokemon Legends: Z-A, you’ll need the Ampharosite, a special item you get while playing through the main story. Mega Evolution makes Ampharos much stronger, so if you caught the shiny Mareep during Side Mission 17 and have it in your team, you’ll want to find this item as soon as possible.

Finding the Ampharosite is actually quite simple once you understand the steps. Here’s how to do it:

You can get Ampharosite by defeating Rogue Mega Ampharos in Main Mission 23, located south of . This mission unlocks after you finish Main Mission 20, “A Request from the Rust Syndicate.”

In this mission, players need to go to the Rouge District and team up with Naveen to battle Rogue Mega Ampharos. Once they defeat Gwynn of the Fist of Justice, a holovator to the rooftops – where Rogue Mega is – will open, letting them continue with the mission.

Gwynn’s Pokemon are all Ghost-types, which all have a 2x weakness to Ghost and Dark-type attacks.
