Pokemon GO's evolution can be as simple as using the required amount of candy, but often rarer evolutions will require an evolution item.
These are consumables that can allow you to not only fill out your Pokedex, but also unlock some impressively powerful creatures.
One such item, Dragon Scale, can evolve Seadra into Kingdra, and others too, so it's worth grabbing one.
Here's how to do just that.
Pokemon GO: How To Get A Dragon Scale
There are a couple of ways to get Dragon Scales, but none are guaranteed.
That means you'll want to complete as many of these tasks as possible - especially since you can only use it once.
Arguably the easiest method of earning a Dragon Scale, you'll want to spin Pokestops wherever possible.
Each offers a 1% chance of an evolution item, including a Dragon Scale.
You'll up your chances by spinning Pokestops for seven days in a row, too!

Speaking of PvP, try competing in the Go Battle League for a chance to earn a Dragon Scale as a mystery item.
