>>40574780>Crystal pokemon and crystal typeCrystallization seems to be the only way for a Pokémon to be the new Crystal Type, which adds or replaces the Pokémon's secondary typing. Because of this, Crystal Pokémon are the only ones capable of recieving a Same Type Attack Bonus on Crystal Moves. Crystal Types seems to have no weaknesses or resistances, but oddly enough, other types aren't weak or strong against it either! Crystal Type is a truly neutral type, thus being very powerful. But only Crystal Pokémon can get STAB boosts on Crystal Moves.
