Upgrade

Upgrade Upgrade - Evolution Item

A transparent device that can make certain species of Pokémon evolve. It was produced by Silph Co.

Special evolution items like the Upgrade first arrived back with the second generation of Pokémon, and are now required when evolving Pokémon such as Porygon2 and Porygon2. When evolving these Pokémon, this item is required in addition to the candy, and is consumed when used.

How to get the Upgrade

Upgrade

The Upgrade is obtained from spinning Pokestops and Gyms. There is a very low drop chance of around 1% per spin to receive a Upgrade or any of the other evolution item, and there is an equal chance of obtaining each of the 5 currently available items.

There's no way to ensure that the Upgrade will drop, but with only 4 other items, there's a greater than 50% chance that you'll receive one once you've spun over 250 Pokéstops.

The 7th day streak bonus gives you a very high chance of obtaining one of the evolution item, but it's not believed to be guaranteed.
