lvl 42.
you have to train it to level 40 for it to be into Glalie
It depends if you have a male or a female. Males evolve into Glalie at 42. Females evolve into Froslass with a Dawn Stone.
Glalie: Level 42 Froslass: No level--if female simply use 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.
Snorunt evolves into Glalie at level 40, or a female Snorunt will evolve into Froslass when exposed to a dawn stone.
just train it or use rare candies and when it is level 42 it will evolve into glalie if you want a froslass your snowrunt needs to be a girl and give it a dawn stone oh and you can only get froslass in dimond ,pearl, or platinum but glalie you can get in emerald sapphire or ruby GOOD LUCK
Froslass doesn't exist in the third generation games, so you can't evolve Snorunt into that.
it evolves at level 42 wile being traded -----different person----- actually the snowrunt has to be female to become frosslass that other person is wrong
A dawn stone will evolve a male kirlia and a snowrunt into a frosslass
You can't catch Glailee, but you can evolve Snowrunt into a Glailee after you purify it.
