In RuneScape how do you get 20k for free?

Answer 1

Briefly, you can get some resource and then sell it on the Grand Exchange. For example, you can do mining, woodcutting and fishing, or kill monsters, and sell whatever you get. Search online for something like "Runescape money-making guide", for more ideas.

A fast way to do this is to get a bronze hatchet from the axe shop in Lumbridge, then chop down the trees near the Grand Exchange and sell them there.
