How to make 25mill in Runescape?

Well i dont believe making 25M can be done "quickly" but tell him to get his fishing up for sharks, which bring in a lot. i think magic logs sell for a lot as well (75 eoodcutting i believe) mining ores, all that stuff is basic, but it brings in gold, for sure. just focus on Woodcutting, fishing, and mining and you will be getting your god sword in no time.
