The only feats I’ve seen for ancestries have to do one race. Why not regional ancestries? People from a cold place should be able to survive the cold regardless if they are human, dwarf, or orc. Let’s start.
Cold Tolerance Feat 5
regional ancestry
Prerequisites raised in cold location
You grew up in a land of ice and snow, and it hardened you against the cold. You gain resistance 5 to cold damage.
