It depends if you have a male or a female. Males evolve into Glalie at 42. Females evolve into Froslass with a Dawn Stone.

You can find a snowrunt near snowpiont city and evolve it at level 42
In Pokémon Conquest, the issue with Snorunt not evolving due to having a 56% Link level as well as being equipped with a Dusk Stone is because it does not evolve into Froslass through the use of a Dusk Stone or according to your Link level, you will need to equip a Dawn Stone to your Snorunt and it will evolve into Froslass.

it will evolve at level 21
You can find snowrunt on the way to snowpoint city. It can only be found at night.
