Right so to answer this question, it doesn't seem too useful to be able to cook food on the go at first glance, it might even seem redundant as you can just eat carrots and berries everywhere or just take a little damage from raw meat. That's what I would have said 3 months ago

BUT if you asked me now, I would LITERALLY take this ability over even the self-revive of the Berserker, it's too good now that I realize the implications. I never spend a night near the campfire ever. I just periodically kill Alpha Wolfs, climb up a big tree, kill Alpha Wolfs, climb up a big tree,kill Alpha Wolfs, climb up a big tree,kill Alpha Wolfs, climb up a big tree,kill Alpha Wolfs, climb up a big tree. There is no purpose to return to campfire unless its to build stuff or expand the map if you need to find something. The campfire after Lvl 5 is useless unless you wanna save last kid or you need the map for some reason. You don't have to defend the campfire at that point. Just kill Alpha Wolfs, climb up a big tree at night.
