you can use a water stone on lombre
Sunkern and Gloom use a sun stone Lombre, Staryu, and Eevee use water stones.
you use it, assuming you have a Pokemon that requires a water stone to evolve instead of just simply leveling.
Equip the Warrior with the Stone and then in a battle or a training session, use it on that Pokemon. And voila.
you use it on some water type Pokemon to evolve them. example:pikachu+thunder stone example:polywhirl+water stone example:evee+fire stone example:Roselia+sun Stone example:murkrow+dusk stone a ever stone prevents your Pokemon from evolving
Lombre and etc
