I find myself never having a use for the campfires in the north. If I’m gonna make the trip, I’m gonna bundle up..but my fancy furs are expensive, so I also avoid combat.
If a campfire could warm up a cold survivor, it should also work against a frozen zombie. Maybe if we have a fire lit, they lose their regeneration buff in its radius. Or maybe if we’re able to stoke all three fires, they all lose a hp per second- so we can go on a frozen rampage/power play, until one of the fires go out..
