Beating the Elite Four and becoming the next Pokémon Champion has never been the only goal of the Pokémon games — you’ll also want to catch every Pokémon fill out your Pokédex. Brilliant Diamond and Shining Pearl are no different. Normally you can find Pokémon throughout the world or by trading version-exclusive Pokémon. However, some Pokémon require special methods to evolve or items to evolve. Togekiss is a great example, but luckily evolving your Togetic won’t be too hard.
Your first step to evolving your Togetic is, of course, having a Togepi. However, unlike most Pokémon, Togepi can be a bit of a pain to acquire, so you’ll need to jump through a few hoops in order to get your hands on one. Evolving Togepi into Togetic requires you to max out its happiness so it might take some time. Once you have your Togetic, the evolution process is simple.
All you need to do to evolve Togetic into Togekiss is to use a special evolutionary stone. Togekiss requires using a Shiny Stone. There are quite a few ways to find Shiny Stones, such as using a Pokémon with the Pickup ability. When you have your Shiny Stone, you just need to go into your bag and use it on your Togetic. Now you have a Togekiss and are one step closer to filling out your Pokédex.
