Nothing. An everstone is just a hold item to stop the Pokemon from evolving.
Marill needs to be level 18 to evolve into Azumarill unless holding everstone.
Geodude evolves into Graveler at Level 25, then evolves into Golem when it is traded (unless it's holding an Everstone).
If your marshtomp is level 36 and doesn't evolve either its holding a everstone or you are preventing it from evolving by pressing the B button.
No Pokemon evolves with an everstone. In fact, an everstone negates the effects of evolution if you give it to a Pokemon to hold.
The way to evolve Haunter has been, and will always be, by trading. If you have a Haunter in Pokemon Emerald trade it to Sapphire, Ruby, Fire Red or Leaf Green and make sure he isn't holding an EVERSTONE as that will prevent its evolution.
There are two in granite cave one by going up the steps on the first floor and another by using a mach bike to fully explore the cave.
If Bayleef is holding the EverStone it will not evolve, if it is holding the EverStone and you take it from Bayleef it will still Evolve.
What u do with a everstone is u give it to a Pokemon and it wont evolve
You can get an everstone in the underground by digging into walls. They are not that rare but not too common either.
People gve an everstone to you as a gift,on some occasions.
A everstone? If your talking about a everstone, it makes Pokemon not evolve
