Way of the Ice

Gnome

You have resistance to cold damage, and are naturally adapted to extreme cold (down to an ambient temperature of –30º).
Accustomed to life in the dark, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
You gain proficiency in Survival.
You have advantage on Dexterity (Stealth) checks to hide in snowy or icy terrain.
