Magnezone has been added to Pokemon GO in May 2019, and he is the 3rd evolution of Magnemite. Magnemite evolves to Magneton with 25 candies and then Magneton evolves to Magnezone.
But there is a catch. If you open a Magneton you aren’t able to see an evolve option as you would normally do on other Pokemon.
Then how you evolve Magneto to Magnezone?
There is a trick to evolve into Magnezone. In order, Magneton to be able to evolve, you have to be near a PokeStop with a Magnetic Lure Module active.
Magnetic Lure Module is a specific item that you can obtain from Pokemon GO Shop by spending 200g, and while it’s used on a PokeStop, it boosts the spawn of ELECTRIC, STEEL and ROCK Pokémon for 30 minutes
If you do that, Magneton will get an evolve option and you are able to evolve it, into Magnezone with 100 candies.
Of course, you don’t need to spend 200g for a Magnetic Lure Module. You can scout for a PokeStop with an active one (that’s has been added from another trainer). Then you can go close to it and you will still be able to evolve into Magnezone.
Happy evolving trainers!
