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.
Ralts evolves into Kirlia at level 20.
Level 20.
level 20
Level 20
It evolves at level 18.
In Pokémon SoulSilver, you cannot find Kirlia however you could catch a Ralts in Route 34 and evolve int into Kirlia at Level 20.
first find a ralts then at level 20 it will evolve and then at level 30 it will evolve to gardivoir
Ralts will always evolve at level 20.
