Evolutionary Items

Evolutionary items are instruments that induce evolution upon compatible Pokémon.

While evolutionary items are multi-methodical in how they trigger the evolution, they are all single-use; they will be expended upon successful evolution of your Pokémon. Additionally, they are usable at any level; this makes it much safer to wait until level 100 to evolve your Pokémon if you wish to train on a lesser experience-chart disparity than its evolution, as opposed to the more precarious level-up evolutions that are sometimes nixed depending on server instabilities at the juncture.

They can be subsumed into two categories: evolutionary stones and trade-evolving items; the latter will usually have secondary, in-battle functions, too, which makes them bifunctional Held Items.
