Basic Campfire as an ability is learned the moment you learn the Cooking skill from a Cooking trainer.

When cooking over a campfire, you need to look for something simple yet delicious. I recommend cooking sausages and other types of meat that can be easily eaten shortly thereafter.

The basic campfire is essential to the secondary skill cooking. It is used when there is no other means available such as in town/cities where there is a cooking fire or some such. Basic campfire's are automatically learned when you take up the cooking proffession, and no longer require you to carry flint and tinder. Basic campfire's also give you a tiny buff to spirit, not a lot, but every little bit helps.
