There are several evolutionary items you’ll need to find to evolve your Pokémon. One of these items is Magmarizer. You will find Magmarizer attached to Magby Pokemon which is available exclusively to the Pokemon Shining Pearl game. You will find Magby in the Grand Underground of Pokemon Brilliant Diamond & Shining Pearl (BDSP). This guide shows how to reach the grand underground and the underground hideaway/ Biome, and where you will find Magmarizer or Magby Pokemon.
