In the core series games
If held by a Pokémon that is not fully evolved, raises its Defense and Special Defense by 50%.
The Eviolite only affects Pokémon if their form and species can theoretically evolve in that game.
- If only the regional form of a species can evolve, only the regional form is affected by the Eviolite.
- Meltan is not affected by the Eviolite, because it cannot evolve in the core series games.
- It does not affect Cosplay Pikachu, Pikachu in a cap, or Eternal Flower Floette, because they cannot evolve.
- It does not affect Pikachu, Meowth, or Eevee if they have the Gigantamax Factor, because they cannot evolve.
- It affects male Combee and Salandit (despite them not being able to evolve while females can).
- It still affects Pokémon that can evolve in the current game, even if it is not currently possible to meet the requirements for their evolution. In Pokémon Sword and Shield, Galarian Slowpoke was affected by the Eviolite even before the Galarica Cuff or Galarica Wreath were available. In Pokémon Scarlet and Violet, it affects Ursaring, Stantler, and Hisuian Qwilfish, despite their evolution methods currently being unachievable. In addition, it also affects Dipplin, which currently has no way to evolve.
- If held by a transformed Pokémon, the boost is based on its original species, not the species it is transformed into.
