升級資料 - Evolution Item

西爾佛公司製造的透明機器，可讓特定寶可夢進化。

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

How to get the 升級資料

The 升級資料 is obtained from spinning Pokestops and Gyms. There is a very low drop chance of around 1% per spin to receive a 升級資料 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 升級資料 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.

Other evolution items
