Here are the Runescape skills you should increase to get lots and lots of money in Rune scape. First, smithing gives you lots of money, but it doesn’t give profit if you are buying the ore.
First, do not do the Knight’s Sword Quest until you are at least lvl 20 in smithing, then do the quest, it will help you to rest a little bit, because leveling in lower levels is a lot easier.
Mining ores also get you lots of money. Mining iron can give you 30-50 gp each for the iron, coal for 100-250 gp each, and etc. The ores will also be used for your smithing, so you can level up in smithing and mining at the same time.
Woodcutting is fun and easy, and yew logs will give you about 200 gp each, but a rune axe would be very handy, since the yew tree is very strong and is hard to cut down.
Cooking and fishing at the same time allows you to once again level up 2 skills at once. Fishing is a lot slower than cooking, but if you can fish and cook lobsters, then you would earn lots of profit. Cooking cakes and pizzas will be very handy in the wilderness or in dungeons.
