For The King

“Snow caves” will pop up on the map after you reach the second continent by boat in the Frost Adventure campaign. Randomly one may have an encounter with a Lonely Yeti as soon as you enter which will lead to a battle against it. You’ll have your whole party against it and it’s a pretty easy battle if you’re at least the level of the Snow Cave. The next room has a monk that needs to be freed with a strength check so choose your highest strength character to set then free and the cheevo will pop.
