New Evolution Methods

Pokémon Legends Arceus has got some different mechanics including no hold items and has changed evolution fundamentally. No longer is evolution automatic but needs to be triggered in the Pokémon menu. Any hold item evolutions are now just utilised as if they were stones.

However, there are multiple new evolution methods, in addition to new items. Some of which are included with existing Pokémon so they have two methods.

Item Evolutions

There are several new evolution methods through items in the game, including some older Pokémon who have changed their evolution method to use a stone. Some of these have a certain extra condition
