Roselia evolves into Roserade when exposed to Shiny Stone.
It differs from Pokemon to Pokemon.
You need a Shiny Stone to evolve Roselia into Roserade.
All you need to do to evolve a Roselia is use a shiny stone on it. No trading, and it will never evolve on it's own no matter what level you get it to.
Roselia do not evolve by level. Roselia evolve into roserade when a Shiny Stone is used on it.
There is no specific level that a Budew will evolve at. However, if you level it up on high happiness, you will end up with a Roselia. And if you use a Shiny Stone on the Roselia, you will get a Roserade.
I think you're referring to Roselia, so it doesn't evolve at any level. You have to use a Shiny Stone on it to make it evolve.
Roserade doesn't evolve. If you mean Roselia, you need to use a dawn stone on it to make it evolve.
Roselia only evolves once you give it the Shiny Stone.
You'll need to make it have high happiness/friendship during the day to make it evolve into Roselia.
I would do it at level 25 but its up to to you
Tauros does not have any evolutions and will not evolve at any level in Pokemon Soul Silver.
U have to level it up first to evolve it
