Firemaking

Firemaking is one of the most useless skills in the eyes of the Runescape community. But it is a very quick 99 to get. You will have to light fires with Firemaking. You can cook your meat and fish on these fires with the Cooking  skill. You don't have to run all the way to those ranges. This is very useful while traveling. You can catch your fish, cook them on a fire and continue to the area where you want to kill monsters. This saves a run to a bank.
