From Pixelmon Wiki
Z-Crystals are a type of held item that allow Pokémon to use a Z-Move of the same type. It can be either damaging when a Physical/Special move is used, or a booster for Status moves. Moves, abilities or items like Embargo, Klutz or Trick can't make a Pokémon drop the Z-Crystal that it's holding. There 24 types of Z-Crystals and some are exclusive to certain Pokémon. They can be obtained as Beast Chest loot in Ultra Space, as drops from rare Boss Pokémon or as drops from specific Pokémon. Z-Crystals can also be used to change the type of Arceus.
