Today I will share with you my experience on how to evolve Gengar in Pokemon LeafGreen 386 Ghoststone. I hope it will be helpful to you.
The evolution of some elves is related to their levels. They can evolve when they reach a certain level, so we have to level up before they can evolve.
However, the evolution of some elves is also related to the degree of intimacy. When the degree of intimacy is reached, they will be upgraded. You can use some props to increase the degree of intimacy.
Some elves can use props to evolve, such as Fire Stone, Moon Stone, etc.
To evolve Gengar from Ghost Stone, the level needs to be level 40. You can use stones when evolving. Patience plus patience or patience.
If you don't upgrade for a long time, it may be because the elves carry the Stone of Immutability, which prevents the elves from evolving.
