Would make sense if fires would fade out so that they give smaller and smaller
ticks before the fire totally goes out.

Then make fire building work so, that you could 'use fire building at camp
fire' when the fire starts fading. ->

"You gather around for some dry twigs and sticks and toss them in the camp
fire. As flames begin consuming the wood the camp fire starts to blaze with
new joy, giving warmth and light." or so, blah.
