at lv 20 that is when ralts evolves
at level 20 Ralts can evolve into a Kirlia
Ralts evolves into Kirlia at level 20. If you are looking to evolve it into a Gallade use a Dawn Stone on a male Kirlia and if you want a Gardevoir just level it up to level 30 is what one of my friends told me.
In Pokémon SoulSilver, you cannot find Kirlia however you could catch a Ralts in Route 34 and evolve int into Kirlia at Level 20.
